Scatter Plot (0,0) problem

[User (Legacy)]

Hi,

I am using ChartFX on ASP and SQL server to plot a graph with

Gallery=SCATTER. I would like to plot 3 series like:

ChartFX.OpenDataEx COD_VALUES,3,COD_UNKNOWN

ChartFX.OpenDataEx COD_XVALUES,3,COD_UNKNOWN

While not RS1.EOF

'1st series

ChartFX.ValueEx(0,j) = RS1("something")

ChartFX.XValueEx(0,j) = RS1("something")

ChartFX.Series(0).MarkerShape = MK_DIAMOND

'2nd series

ChartFX.Series(1).Yvalue(j) = rs2("something")

ChartFX.Series(1).Xvalue(j) = rs2("something")

ChartFX.Series(1).MarkerShape = MK_TRIANGLE

ChartFX.Series(1).MarkerSize = 5

j=j+1

rs1.MoveNext

Wend

'3rd series

Do Until rs3.EOF

ChartFX.Series(2).Yvalue(st) = rs3("something")

ChartFX.Series(2).Xvalue(st) = rs3("something")

ChartFX.Series(2).MarkerShape = MK_RECT

ChartFX.Series(2).MarkerSize = 2

st = st + 1

rs3.MoveNext

Loop

ChartFX.CloseData COD_XVALUES

ChartFX.CloseData COD_VALUES

This code produces an additional marker (caused by the 3rd series) at (0,0)

when there is no such value. How can I prevent this?

Pl. let me know if you need any other parts of the code to understand the

problem better.

Thanks!

The problem seems to be that the third series is "shorter" than the others.

In Chart FX 5 ALL series have the same number of points, so the rest of the 

points are being filled with zero (0).

What you need to do is hide them by filling them with CHART_HIDDEN as the 

Y-Value (X-Value can remain at zero).

So after your last loop, you need to do this:

....

st = st + 1

rs3.MoveNext

Loop

While (st < j)

    ChartFX.ValueEx(2,st) = CHART_HIDDEN

    st = st + 1

Wend

While (j < st)

    ChartFX.ValueEx(0,j) = CHART_HIDDEN

    ChartFX.ValueEx(1,j) = CHART_HIDDEN

    j = j + 1

Wend
