What steps will reproduce the problem?
1. Create a pie chart
2. Add data with high numbers (>100000)
3. The url is wrong (lacks of the querystring parameter for the data) and
graph is not displayed

Using current version (1.0.2)

According to http://code.google.com/apis/chart/#required_params
the Barchart does support Grids. But I do get an
"InvalidFeatureForChartTypeException" when I try to set one.

Looks like SSL certificate is invalid. I don't have Google's contacts, so maybe 
you could help :-)

What steps will reproduce the problem?
1. https://chart.apis.google.com/chart?cht=lc&chs=150x150&chd=s:AKUeo

What is the expected output? What do you see instead?
Expected image. I get SSL certificate error (certificate not valid for 
subdomain)


What version of the product are you using? On what operating system?
Any

Please provide any additional information below.

What steps will reproduce the problem?
Create a BarChart that uses the extended encoding. E.g. create a chart of
200x200 pixels and use values above 63 so that extended encoding is used.

What is the expected output?
A normal bar chart that is properly scaled.

What do you see instead?
A chart with very tiny bars.

What version of the product are you using? On what operating system?
1.0.2.

Please provide any additional information below.
I've created a patch, see the attachment.

I have this float array of data:
    float[] { 0, 3.75F, 18.75F, 50, 37.5F, 62.5F }
And GoogleChartSharp generates an URL including this:
    chd=t:0,3,75,18,75,50,37,5,62,5
But it should look like:
    chd=t:0,3.75,18.75,50,37.5,62.5

See the attachment for a diff.

Compound chart types are not currently supported. Possible solutions:
1. Modify current  type BarChart to add compound parameter
2. Add dedicated CompoundChart type
I have looked at the source code and have an implemented partial solution
for BarChart (only supports line types added) 

Hi!

First thank you for this nice converions of Google Charts into C#!

I ve recognized a problem within the simpleencoding algorithm! I get wrong
images back.

You make the choosen encoding type dependet of the max value found in the
dataset. I would suggest to make it dependent of the width and height of
requested image. As for 300 x 250 61 values should be enough detailed.

i would suggest to take the orignial code snipped of the google developers
guide to do the simple encoding.

        public static string SimpleEncoding(int[] valueArray, int maxValue)
        {

            string simpleEncoding =
"ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789";
            char[] arr_simpleEncoding = simpleEncoding.ToCharArray();

            string chartData = "";
            for (int i = 0; i < valueArray.Length; i++)
            {
                int currentValue = valueArray[i];
                if (currentValue >= 0)
                {
                    char curr_c =
arr_simpleEncoding[Convert.ToInt32(Math.Round((double)(simpleEncoding.Length -
1) * currentValue / maxValue))];
                    chartData += curr_c;
                }
                else
                {
                    chartData += "_";
                }
            }
            return chartData;
        }

hope this helps.

What steps will reproduce the problem?
1. Set the grid to a decimal value : .SetGrid(4.2f, 50);
2. Display the graph on a European computer (or any language using , as a
decimal separator)
3. The grid is not displayed correctly because the URL is damaged

What is the expected output? What do you see instead?
A correct graph, a damaged one.

What version of the product are you using? On what operating system?
1.0.2 / Windows

Please provide any additional information below.
The issue is partially fixed for problems on data in
http://code.google.com/p/googlechartsharp/issues/detail?id=13 but it only
fixes the data part, but it can happen on any parameter that allows decimal
values.
One fix would be to replace every .ToString() by a
.ToString(CultureInfo.InvariantCulture) but I preferred changing the thread
culture during the .GetUrl() (less code).

Let me know if you have any questions on this issue.

What steps will reproduce the problem?
1. Create a chart
2. Call GetUrl()
3. Run resulting web page through xhtml-validator

What is the expected output? What do you see instead?
I expect & to get encoded as & to safely use it as src-atrribute in img-tag.

What version of the product are you using? On what operating system?
1.0.2 on Windows XP

Please provide any additional information below.
Please add an optional parameter "bool encodeOutput" to the GetUrl()-method.

What steps will reproduce the problem?
1. Search Documentation for the word Table
2. Note how many results are found

What is the expected output? What do you see instead?
  Would like to be able to use this wrapper to produce a Table (aka Grid Control) as documented at http://code.google.com/apis/ajax/playground/?type=visualization#table

What version of the product are you using? On what operating system?
 Just searching the documentation for Table support before learning investing time to learn this code. Date: 10/19/10 latest version 1.0.2.

Please provide any additional information below.
 I really need to use google chart tables and don't think I'll use it unless it has table support.

When I using Bar Chart and put SetGrid directive, the site does not open
and show a error.

I changed the if to:

            if (!(chartType == ChartType.LineChart || chartType ==
ChartType.ScatterPlot || chartType == ChartType.BarChart))
            {
                throw new InvalidFeatureForChartTypeException();
            }


PS.: Have 2 places to change!

What steps will reproduce the problem?
1. Required API that helps to specify exactly which encoding I want to use.

What version of the product are you using? On what operating system?
2. latest

Please provide any additional information below.
Found issue: when used not "Text encoding" chart do not scale chart
properly. Required API that helps to use workaround;

What steps will reproduce the problem?

1. Checkout source from SVN
2. double click ".sln" file

Is this api use for windows application or other api available for free?

Hi this is my example and patch file
http://chart.apis.google.com/chart?cht=lc&chs=700x200&chd=t:48,57,53,49,40,5,3,2
1,41,100,60,75&chtt=Annual+Summary&chts=000000,14&chxt=x,y&chxl=0:|January|Febru
ary|March|April|May|June|July|August|September|October|November|December|1:&chxp
=&chxr=1,0,86552&chxs=&chm=B,EFEFEF,0,0,0

Added a version of SetRange that takes the new optional interval parameter.
A test was added to demonstrate the functionality.

Patch file is attached.

Thanks for the very useful library!

The relatively new Maps chart would be nice addition.

Attached is my first stab at it because I do not know how to officially
submit code.

I have to say that I don't like hex at all.
Therefore, I create a new version of SetDatasetColors which use Color array
as parameter instead of a series of hex string.

Well, this is the code, hope it useful for some one ^^ (me, at least).

/// <summary>
/// Set the color for each dataset, match colors to datasets by
/// specifying them in the same order the datasets were added to the
/// chart.
/// </summary>
/// <param name="datasetColors">an array of <see
cref="System.Drawing.Color"/></param>
public void SetDatasetColors(Color[] datasetColors)
{
    string[] colorHexArray = new string[datasetColors.Length];

    for (int i = datasetColors.Length - 1; i >= 0; i--)
    {
        colorHexArray[i] = ColorToHex(datasetColors[i]);
    }

    SetDatasetColors(colorHexArray);
}

/// <summary>
/// Convert <see cref="System.Drawing.Color"/> value to Hex value.
/// </summary>
/// <param name="color">A value of type <see cref="System.Drawing.Color"/>
which you want to convert in Hex value.</param>
/// <returns>Hex String</returns>
private string ColorToHex(Color color)
{
    return String.Format("{0:X2}{1:X2}{2:X2}", color.R, color.G, color.B);
}

Please, in ChartData.cs change the ToString() call in the function 
textEncode(float[] data) with this: 
value.ToString(System.Globalization.CultureInfo.InvariantCulture.NumberFormat) 
for work in systems with a different decimal separator.

Thank you

What steps will reproduce the problem?
1. Using float[] with decimal values in chart
2. Swedish (or other) i18n rules

Expected output is for example 1.10, but as we Swedes use the decimal
separation character "," (instead of the expected ".") the output is "1,10".

This screws up the URL as each float value is separated with a ",".


Using the 1.0.2 version (sourcecode) on Windows XP with .NET 3.5 (Swedish).

Fixed the problem by adding a .Replace(',','.') call after the ToString.
ChartData.cs, line 122:

chartData += value.ToString().Replace(',', '.') + ",";

However, unsure how to fix this to be culture non-specific.

Cheers!

I've been having trouble scaling a stacked bar graph to the correct size
and getting it to match the values on the x-axis.  The x-axis data labels
show a max of 100 despite my data going up to 750, and the bars are only
about 1/4 as wide as the chart.  What's also strange is that if I take the
same data and use a float data type, then the bars are too wide and are
cropped off the right side of the image.

<code>
string GenerateChart_Int()
    {
        BarChart Graph = new BarChart(500, 500,
BarChartOrientation.Horizontal, BarChartStyle.Stacked);
        int[] data1 = new int[] { 668, 306, 158, 130, 100, 92, 80, 76, 65,
55, 45, 31, 21 };
        int[] data2 = new int[] { 68, 50, 18, 10, 12, 9, 17, 6, 9, 5, 5, 4,
1 };
        string[] labels = new string[] { "A", "B", "C", "D", "E", "F", "G",
"H", "I", "J", "K", "L", "M" };

        List<int[]> datasets = new List<int[]>();
        datasets.Add(data1);
        datasets.Add(data2);
        Graph.SetTitle("Chart Title");
        Graph.SetBarWidth(25);
        ChartAxis yAxis = new ChartAxis(ChartAxisType.Left, labels);
        ChartAxis xAxis = new ChartAxis(ChartAxisType.Bottom);
        Graph.AddAxis(yAxis);
        Graph.AddAxis(xAxis);
        Graph.SetDatasetColors(new string[] { "88AAEE", "FF3333" });
        Graph.SetData(datasets);
        return Graph.GetUrl();
    }
</code>

This generates this graph - <a

If I use the same data with the 'float' data type, it generates this graph
<a
href="http://chart.apis.google.com/chart?cht=bhs&chs=500x500&chd=t:668,306,158,1

s=&chbh=25">floatoutput</a>

Two separate graphs, same data, both useless.  I just want the width of the
image to match the width of the data and have it match the labels on the
x-axis.  Any ideas?

Add the following sequence to a char: new [] { 1.5 } and switch the 
currentculture to "DE-de". You will get two datapoints because then umber 1.5 
gets encoded as 1,5.

The fix for this is to find all places where you convert a number (int or 
double) to a string and do it like this: 
1.5.ToString(CultureInfo.InvariantCulture)

You also need to find places where ints are converted because users can 
configure custom integer formatting in their windows and add 
thousands-separators and the like.
