Scatter control [message #61365]

On y axis scale, scientific notations are shown default (not mentioned in code to show in exponential form). I want to display the value in floating point numbers only, not in exponential form.

In the image attached, the scale values on y axis is say 4E-2. I want to display the value as 0.004.
How can i do it in scatter control.

Thanks,

Hi Pallavi

Scatter chooses the format, scientific or not, that gives the most information about the number within the available space.
If this doesn't work for you, you can always use the cbModifFormatY() callback. For example this will display numbers to three decimal places:

myScatter.cbModifFormatY = [](String& ret, int, double num) {ret = Format("%.3f", num);};

Hi Pallavi

I have just uploaded a sample of this in examples/ScatterDraw_demo_cl.

Best regards
