What steps will reproduce the problem?
1. Modified ChartDemo's BudgetPieChart.java to change data legend title
from "Project" to "Events".
2. The legend shows "Project-1 ... n, no matter what title you use in the
call to buildCategoryDataset at line 55.
What is the expected output? I expect to be able to change the legend with
the dataset values.
What do you see instead? The legend for the data series is always "Project-1 ..
n.
Please provide a source code snippet that we can use to replicate the issue.
Line 55 was:
return ChartFactory.getPieChartIntent(context, buildCategoryDataset("Project budget", values), renderer);
I changed to:
return ChartFactory.getPieChartIntent(context, buildCategoryDataset("Events Percent", values), renderer);

I like your new pan/zoom functions! I don't know what is on your todo
list, but I like the option to only zoom horizontal (or vertical for
other people). This is because I have a lot of data I want to display,
wherein the max/min Y values are staying the same, but the x-ax is
getting more points, the more time the app is recording.
I fixed this manually, by just removing the zoomparts and pan parts
for the y-axis, but maybe more people would like this function.

I expect the data to pan to the right, but that doesn't work. Before I pan
fully to the left, I can also pan to the right..

Please provide any additional information below.
- I have set only X-panning and have set a limit for panning. The limit works,
but stops working when panning to the left (to zero).
I don't know if I'm doing something wrong, or this is a bug..

I created a chart, and because I would like to have the background white, I was
wondering if it was possible to either have the labels moved slighly to the
left, so they no longer appear in the chart, but only left to it, or have an
option to change the background color beyond the chart area.
Other than that very good library created here:)

When panning, you can keep on panning, beyond the limits. It should probably be
better to set limits for panning.

Enhancement request for the legend to only be as large as it needs to be.
Currently it is either controlled directly by the end-user or defaulted to 1/5
of the chart's height.
I directly include achartengine's source code in my app's source code, so if I
end up implementing this, I'll refer you to my solution.

Hello!
I found you library some days ago when i was looking for a chart library for
android. i tried it in a small project and i liked it at once.
Espacially the Zoom feature looks good. The only thing I miss is the
possibility to zoom with "pinch to zoom", not only with the buttons.
Do you have planned something like this?

Harald

Android 1.5:
Could not find method android.view.MotionEvent.getX, referenced from method

Using achartengine-0.6.0.r140.jar
Is there a way to avoid this?
Or maybe achartengine explicitely does not support Android 1.5?

You need to replace ArrayList<Double> in XYSeries.java on TreeMap<Double,
Double> and do every consequent action.
The only visible part of chart should be drawn. Now it paints all the chart, no
matter if you can only see 5% of the chart by zooming.
I replaced array lists by maps. Before it started to work slow after 2000
points. Now no matter how many points there are there, it works as same as in
the beginning. Here's the code http://pastebin.com/JHnaLUsB
it's not perfect, but you can get the main idea.

This library is actually quite good. I initially discounted it because I saw
the screenshots and it looked ugly. After downloading it and playing with some
of the options, you can actually make some pretty eye-popping graphs out of
this thing. And the API is simple to figure out.
If you update your screenshots, more people will use this awesome library!
Thanks for putting this together.

with the new, zoom-enabled library, the GraphicalView does not call the super's
implementation of onTouchEvent, which causes a loss of functionality.
For example, I want my application to launch an activity if the chart is
selected, but using the new library, this event will be caught by your code.
even if pan/zoom is disabled, I cannot use a touch/click/select event.
Please add:
return super.onTouchEvent(event)
instead of 'return true', so the default behavior persists. It might be good to
skip the above call if pan/zoom are enabled (i.e. return true in the if()
block).

What steps will reproduce the problem?
I have a Scrollview with some other views inside and a chart at the top.
When I scroll down and the chart gets out of screen at the top, it suddenly
shrinks, because it wants to fit in the remaining space.
I looked at the code and changed the following thing to fix it for me:
In GraphicalView.java, Method onDraw at the beginning
canvas.getClipBounds(mRect);
int top = mRect.top;
int left = mRect.left;
int width = mRect.width();
int height = mRect.height();
to
int top = 0;
int left = 0;
int width = getMeasuredWidth();
int height = getMeasuredHeight();
Now the chart just scrolls out as expected.
Cheers,
Harald

Please provide a source code snippet that we can use to replicate the

Hum.. The last one ??
Please provide any additional information below.
Actually, I kind of fix it :
Changing graphicalView from :
@Override
protected void onDraw(Canvas canvas) {
super.onDraw(canvas);
canvas.getClipBounds(mRect);
int top = mRect.top;
int left = mRect.left;
int width = mRect.width();
int height = mRect.height();
mChart.draw(canvas, left, top, width, height);
}
To :
@Override
protected void onDraw(Canvas canvas) {
super.onDraw(canvas);
canvas.getClipBounds(mRect);
int top = mRect.top;
int left = mRect.left;
//int width = mRect.width();
//int height = mRect.height();
int width = canvas.getWidth();
int height = canvas.getHeight();
mChart.draw(canvas, left, top, width, height);
}
Note that it implies that the full graph view will be drawned every time,
even if half of it is hidden. But I don't think it is such a big deal...

Hi, thanks for sharing this library to android world,
I have one problem when use pie chart today.
In the source code of AbstractChart line 15 in drawLegend()
I saw , currentY += 15;
this is not right cause I will set the font size large than 15px in high
resolution device, if I do so, for example set to 32px, the legend text will
overlap each other.
I think the increase of currentY should depends on legend text size not 15,
thanks.
