    Generate line chart from a CSV file using numbers as X/Y axes (use two or more measure units for Y axis)

    Reply Contact

    I have a CSV file below:

    sequence,value,increment

    1,1000000,0

    2,1000010,10

    3,1000030,20

    4,1000060,30

    I want to generate a line chart w/ field 'sequence' as X-axis and field 'value'/'increment' as Y-axis.

    How to do that?

    It is quite simple if the value for field a is string rather than numbers.

    Besides, I want to use different measure units for field 'value' and 'increment' as the value of 'increment' is far less than that of 'value'

    Thanks in advance~~~

     It is quite simple. You use Bresenham's line drawing algorithm. You will need to use BitMap class to render the image.
