Histogram Charts

[ChrisM 24]

Hi All

I am trying to create a histogram chart of data values which upates itself
every time a new value is added to the set of data, which is every 2 secs.

From the examples I have managed to butcher a VI to meet my functional
requirements. However, can anyone tell me how to rotate the chart 90 degrees
anti-clockwise so that it looks like a Bell Curve chart, and not one on its
side.

Also, I would like to display limit lines so that an operator can take
appropriate action if the curve is displaced from the nominal value too
much. Can anyone tell me how to achieve this on this type of chart.
Thanks in advance.

Yours sincerely, Chris McCrory Project Engineer

You haven't attached your VI or said which example you "butchered" so what I have to say may not apply exactly. If you are doing something like the example VI called Running Histogram Example that has the bars going horizontally, to display them vertically, first swap the arrays going into the bundle function. Second, right click on the plt legend, select bar plots and select a vertical style. To add limits to an XY graph, create a couple of array constants that represent your limits and bundle them into the graph along with the histogram. The example XY Graph.vi shows how to accomplish multi-plot XY graphs.
