How declare attrs of graph in style.xml?
I want decrare this attrs in style.xml and dynamically create charts with this attrs

    app:egUseCubic="true"
    app:egUseOverlapFill="true"
    app:egCurveSmoothness="0.4"
    app:egIndicatorColor="#FE6DA8"
    app:egLegendHeight="40dp"
    app:egShowStandardValue="true"

How to update PieChart's PieModel value on Resume?

I try to reloadView(), clearChart(), destroyDrawingCache() before add again, but it does not work.

There used to be a BaseChart.OnUpdateListener in some previous version. Where can I find similar functionlaity now

When i touch barchart (not clicked. e.g, swipe), onclick event is fired

It's can be greate if bar charts can be clickable

When I make a new BarGraph that has padding and labels at the top, the padding does not look at the height of the label and add the difference.

The README shows for the Line Chart app:egIndicatorColor, which should be app:egIndicatorLineColor :)

My build.gradle contains the following:

repositories {
mavenCentral()
maven {
url 'https://oss.sonatype.org/content/groups/public'
}
}

Am using the pie chart in a view pager so the rotation can't work for me. Was wondering if I click click on a pie slice and the legend can rotate there. Thanks

Hello,diogobernardino !!! Thank you for library, it is awesome. I was wondering if i could get info (like its label and value) about the bar i clicked.

like that

thank you in advance!

How can I remove legendLabel and Arrow icon from Bottom of PIE chart ?
I don't want to have startup Animation in PIE chart , Is there anyway to disable it ?

        LayoutInflater inf = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        LinearLayout ll = (LinearLayout) inf.inflate(R.layout.layout_pie_chart, null, false);

The repository works great.
But on some of the android devices running Lollipop (4 out of 9 devices), the initial rendering of animation of PieChart isn't done in a proper manner.
The animation blinks while rendering.

For example I set barmodel value to 1561456.11, but I want to show to user as 156,145,6.11.
Provide String value in constructor, that will be shown to user.

Is there any way, or any easy way I can implement a way of specifying a minimum and maximum height for bars in a bar chart?

The data that I am rendering is always going to be between two values, but the app dynamically loads the data every second so when the first value is loaded it currently appears full height given there is no other data to compare to. The data is a temperature reading as well, so if it doesn't fluctuate a large amount, then the bars will continue to be full height until it spikes a lot.

What I want to do is have the height of the bar be relative to the min and max values I have rather than be adjusted according to all of the data. How could this be implemented?

Is there any chance to see this library at the Central repo, not only at the snapshots one?

Calling the clearChart() method on a BarChart object calls BaseBarChart::calculateBarPositions(0) which results in the mentioned exception

Also, please consider supporting BarCharts and StackedBarCharts without labels.

Are there any plans to add y-axis labels and a drawing grid to this excellent library? By grid I mean a bunch of horizontal lines that indicate the value of the bar/line at certain labeled points on the y-axis.

No resource identifier found for attribute 'egIndicatorLineColor' in package

when I add this attribute in layout xml
I got above error,how can I solve this issue,thanks

It would be nice to have a way to prevent the Legend object to be added to the charts. I need the pie chart without any legend but can't get rid of that triangle ;)

I've found some strange behaviour with the setUseOverlapFill(boolean) method for the ValueLineChart. If only one serie is added to the ValueLineSeries it always fills the area under the graph, even when mUseOverlapFill is set to false.

I don't know if this is intended behaviour, but it feels kind of strange. I believe it can be fixed in line 801 of the ValueLineChart class by removing the seriesCount check:

if (mUseOverlapFill || seriesCount == 1) {
    path.lineTo(mGraphWidth, usableGraphHeight);
    path.lineTo(0, usableGraphHeight);
    path.lineTo(firstX, firstY);
}

I want to make bar in horizontal bar chart curved. Can you please help me.

HI Paul,

we are using your chart, but still have a problem to start a drawing from the middle without a 0 point.

I want to start a line from 1000 point not from 0 to 1000

how to do this? please help

e.g:
pieChart.setValueTextColor(Color.parseColor("#ffffff"));
pieChart.setLegendColor(Color.parseColor("#ffffff"));

They don't work. Even calling pieChart.update(); doesn't update the colours.
Calling these functions before pieChart.startAnimation(); also renders the functions unresponsive.

Hi!
If BarChart has all barModels with value 0 - 0 is not shown? Why bars have such behavior and where can I fix this?
thanks

Hey,

I'd like to display dynamically some big textes (20-30 Chars) in piecharts legend. At the moment I get only one line for legend and because of that some characters are occasionally unvisible.

I have tried 2 solutions:

1. set programatically the correspondent textview to "singleline=false" and use line separator.
   But I didn't find this textview.
2. get length of current label in "onItemFocusChanged" and then set correspondent textsize to legend:
   pieChart.setLegendTextSize(size);
   pieChart.reloadView();
   But it didn't change anything..

p.s.Thanks for this beautiful library!

I am using the latest non-interactive version of EazeGraph, which I think is really simple and amazing. But I need some help on the following issues.

From the picture above, we can tell that the Y values are 0, 1, 3, 5, instead of 0, 2, 4, 6. And the highest point of the red curve is a little bit lower than expected(the actual value is 7.5).

Besides, when app:egUseCubic="true", this deviation becomes larger as the value of app:egCurveSmoothness goes higher. Below is a graph whose app:egCurveSmoothness is 0.4.

Here is a part of the XML layout file:

    <org.eazegraph.lib.charts.ValueLineChart
        android:id="@+id/chart"
        android:layout_width="match_parent"
        android:layout_height="200dp"
        app:egUseCubic="true"
        app:egCurveSmoothness="0.4"
        app:egXAxisStroke="0.1dp" />

So is there anything I missed to do this right?
Thank you in advance.

When I am using eazegraph barchart inside horizontalScrollView than graph is not shown.My requirement is that I am using graph inside viewpager so will u solve this problme...

Provide .jar file or eclipse project to incldue as dependency

It should be an aoption to disable animation, or set custom animation when graph is loaded.

Hello Paul.
I'm using your chart.I have one question about LineChart.is it a possible to disable(remove) zooming action in LineChart?
thanks

A method to change the color of the bar?

Hello,

how can I set X axis range. I want to set it fixed, now it is dynamic.

or how can i show graph only in specified location for example from 1 to 6 point. Because then, i can set 0 point to my min, and x point to my max and show graph from 1 to (x-1) point.

Best regards. Eliah.

My graph is crashing when i pinch zoom it without the property set in xml:

    app:egShowValueIndicator="false"

and if i set it to true it suddenly stops crashing.
And i want to stop pinch zoom what is the xml or java property to stop that ? I have tried touchListener to null but it is not effecting the situation.

Hi,
Thanks for this library.
I am trying to do the multiple line charts in single graph view. I am adding different series to mCubicValueLineChart. But here IndicatorLine is not working. Please fix that issue.

I want it to be transparent and just show the lines of the ValueLineChart

Hello,
I add bars but the legends do not appear yet I use the appropriate constructor finally in my opinion.
`arChart mBarChart = (BarChart)dialog.getCustomView().findViewById(R.id.barchart);

    mBarChart.addBar(new BarModel("Moudjames23", 2.3f, 0xFF123456));

`
Thank you in advance for your answers.

like title.

There is a problem with it.

I'm trying to use the setOnBarClickedListener(IOnBarClickedListener) method to highlight a bar by changing its colour. However, the StackedBarChart only redraws after moving the graph. Would it be possible to redraw the bar after the click without moving the graph?

Hey, first of all great work, loving the library. So the thing is right now, I can't find a way to set maximum value for Y axis. Is there any way i can achieve that?

Hey there,

I met a problem when I try to zoom out the chart. Seems I did not pass the touch event correctly.
How do I pass value to mFocusedPoint so that I can solve this error...the action was 2 fingers zooming out

Method to change the x-axis

Is it possible to display only first and last value on X axis? and remove line above values in X axis

I've run into an unusual issue with the chart I'm rendering. I've got a standard bar chart which is updated by adding one new bar every second. What I've noticed however is that every time a bar is added, the entire chart appears to shift to the left ever so slightly, perhaps 1 px every 2 bar additions. In the long run, this results in the chart being invisible as it is pushed off the side of the screen.

I've tried debugging the code but I'm unable to determine where the issue lies but it is quite a problem.
