Hi ,i want to draw a chart of this type,how to do it,I tried it.Is there any simple charts like this,pie chart etc

how to do it

You cand use Canvas class and it's drawing functions. The one that suits your need it's the old basic DrawLine:

public void drawLine (float startX, float startY, float stopX, float stopY, Paint p);

First you draw the axis, two lines, then the values across the line. The data which must apper in the chart is stored in some way in memory. All you have to do is convert this values into the units of the chart. For example you decide that for Y axe 1 pixel is 10 units (10 pixels = 100 units, as an example to your picture). Same goes for X axis too. So you scale your data by a factor of 0.1 (divide by 10.0) to obtain the Y coord in pixels relative to the chart origin.

For pie charts you can use Arc and Oval shapes.

Similar problem. I have ten number which I wish to use them to draw a beautiful chart.

Will it be easier if using OpenGL to draw line chart or bar chart? If yes, how to do it.

I am new, drawing it by self is too complicated for the novice like me.

Thanks in advance.

I suggest you to take an android sample from the SDK that draws something on the screen using Canvas class and try to understand it (look up for the the initialization of the activity and the canvas class then the function that does all the drawing, etc). After that, all you have to do is do your stuff with lines, rectangles, circles, etc. It's not really complicated, but you have to start from somewhere, that's why i suggest you to load, compile and understand a sample from the SDK.

Hello Sir,can u tell me which sample pgm to refer,so that i can get an idea of it

For a working Canvas example you can look at the Lunar Lander demo.
The path is: android-2.0.1 > samples > LunarLander

For other graphic examples, you cand search and read from the source files found here:
android-2.0.1 > samples > ApiDemos > src > com > example > android > apis > graphics
