Histograms

[epm...@gmail.com]

How do I get a Histogram - i.e. vertical bar-chart, with x-axis values as, say, 50,100,150,etc., and y-axis values as 1000, 2000, 3000, etc.? (i.e. x and y intervals are different, and they ought to be displayed on the respective axis). These intervals are dynamic, and come from calculated variables (hence, cannot hardcode the bounding box also)

Thanks in advance

Hello

This example will help:

To change bounding box after you know the min and max, use e.g.:

var xDataMin = -2, xDataMax = 5, yDataMin = 0, yDataMax = 3000;
board.setBoundingBox([xDataMin, xDataMax, yDataMin, yDataMax]);

Thanks Murray, but this is what I have in mind (Refer image).

The x-axis could, maybe, even start with 100--110--120--130-- etc.

Hello again

You could create your own axes to achieve this. See this page for some ways to go about doing it:

Thanks Murray, I guess that shows me the way. Shall try it out.
