Plot of a 2 dimensional array

[Leope]

hi,
I am looking for a way to plot a 2 dimensional array in my indicator
For example the "X" scale is of stock with price range from2-8 and the "Y" scale is some metric or a price of a different stock ranging from 500-1000
The outcome should like some kind of histogram , as in the attached drawing - so I want to be able to plot only certain data from the array, excluding null data.
can you point me on what I need in order to accomplish this ?
Thanks

Hello Leope,

From your description it sounds like you would want to use a normal Plot. Plots are 2 dimensional in the sense that they have a specific number of X slots or your Time scale and then a Price for each slot. You cannot change the X scale to be like you pictured to have custom values so you would need to use Time/Bars.

A Plot does not need to have a value for each bar so you can not plot a value to make an Invalid data point. Invalid data point are not rendered.

If you wanted to draw the data in a different way than a normal plot you could use OnRender to draw within the panel to make your own numbering on the X axis however your actual X axis would still be time based, based on the data series settings of the chart.

The indicator SampleCustomRender demonstrates some basic rendering concepts.



I look forward to being of further assistance.
