setAutoGenerated(true) with Date values about hellocharts-android

Hi, not sure if that's what you need but you can set manual labels for axis, library will hide some of them if there will be no place to display them, that will happens automatically. Look at LineColumnDependency sample in repository, there is X axis with months names, on small screen in portrait orientation some of them will not be displayed but when you zoom in you will be able to see every month name.

yes.. looks like its working that way right now. But my x-axis labels are a little longer and the chart is still showing too many labels at a time, causing overlap. My x-axis date label format is MM-DD-YY. Does the chart caculate the width of labels to decide how many labels to show at a time. Or, can specify the number of items to display on the x-axis?

[lecho]

You can specify maximum number or characters for labels with method Axis.setMaxLabelChars(int), default are 4 or 3.

Thanks that works in the master branch. Doesn't work in the last release version 1.3.

[lecho]

Hmm, that possible, I made some changes in AxisRenderer last month, I will release version 1.4 in the next week.

Great.. another request would be to add a feature to reset the chart's zoom level. May be long press on the chart's viewport.

@jaichandra Please open a separate issue for your feature request and remove it here.

[lecho]

@jaichandra you can already reset zoom:

chart.setCurrentViewport(chart.getMaximumViewport());

I will not add new gesture/touch event for that, you will have to implement it by yourself.
