java.lang.OutOfMemoryError: bitmap size exceeds VM budget (in the charts example)

[mc73]

Hi, I am using the charts example in order to draw three different type of charts in a tabhost (similarly to the example). Now, a bar chart has around 200*4=800 bars, and I get the vm error. Of course I can avoid it by drawing the chart on the fly by forcing a button click (left and right) and invalidating each time the shown part of the chart, yet, I find the horizontal scrollview I'm using, pretty impressive. Any workaround? Here's the full log of the error:

What is the size of the bitmap?

You can create a scaled down bitmap.

I am not in front of my pc for development right now, so I don't know the size. Yet, I am using this example, with no other modification apart from replacing a panel with a horizontalScrollView. I will check the code and try a scae-down, sure!
