Connecting Points in a Scatter Graph
Posted on 2001-07-25
We have a PB 7.0.3 and Oracle 8i (8.1.6) application where we need to graph data in a scatter graph and then connect the points and remove the point symbols. This does not seem to be done easily in the PB Graph control.
Below is an example for the data to be plotted.
First as represented in a row
From Point To Point Data
0 12 80
12 14 100
14 16 (Null - no data for this pair)
16 20.45 95
The list cotinues on in this fashion until the end of the data.
In Excel I can graph a line scatter plot (and get the gap) very easily by representing the data above in two columns as shown below:
We have been somewhat successful in getting lines to draw but it seems that points are not plotted in the correct order and that gaps are missed.
Can anyone provide a reference or example in how to do this in a PB Graph Control?
