Combination Graph - Weird Line


User (Legacy)

Recommended Posts

Hello,

I have a combination graph (AREA, and LINES) with two seperate series. I

also have a graph with just one series (LINES). Examples of both of these

are attached. Both of these graphs are using the exact same data. For some

reason, on the combination graph, the line is not terminating at the last

data point... It's as if there is an extra last data point, that has the

same Y value as the last data point, but has an X value at the origin of the

graph. (Pictures (graphs) are worth a thousand words, check out the

attached images).

I have this same problem with another graph used on the same site. In this

case, the graphs are all LINES. Again, using identical source data, I get

the same weird horizontal lines going back to the origin. The only thing I

changed between the two graphs is the length of time on the X axis (2 hours

of data vs. the last 24). I went ahead and attached those as well.

Any ideas as to what might be causing this?

Thanks!

Brian

There is an extra point in this graph with X = 0 and Y = 0 (default) 

probably because it was left un-initialized.

Check your data. Remember, all series in Chart FX have the SAME number of

points. If you are assigning values for the Bar series beyond the last point

in the line, the line series will be filled with zeros to match the size of

the bar series. If you want to hide these values assign CHART_HIDDEN to

them.

OK, this solved the problem.

Just a suggestion: Maybe the ~default~ value should be CHART_HIDDEN (any

way to set default value?). I would think you wouldn't want a data point

plotting unless you specifically asked for it! When dealing with multiple

series that don't share the same X ordinates, or even the same number of X

values, its gonna gets programmatically expensive to figure out.

Example like my RWIS graphs, I have 4 series I want to plot:

Query max number of ordinates in first series.

Query max number of ordinates in second series.

Query max number of ordinates in third series

Query max number of ordinates in fourth series.

Determine max number of ordinates for all series.

Query data pairs for first series and feed to chart.

Add on CHART_HIDDENs for the remaining ordinates.

Query data pairs for second series and feed to chart.

Add on CHART_HIDDENs for the remaining ordinates.

Query data pairs for third series and feed to chart.

Add on CHART_HIDDENs for the remaining ordinates.

Query data pairs for fourth series and feed to chart.

Add on CHART_HIDDENs for the remaining ordinates.

Maybe there is a much easier way to do this and I'm missing it!

Thanks for your quick response!
