Time Series Plot

Question

Is there a standard way to create a time series chart in Apex 4.2?
The line chart does not take into account irregular time intervals - it assumes that the data points on the X axis are equally spaced, its just really a bar chart but with a line instead.
The scatter chart handles the x axis values correctly but does not have the option to join the points with a line, so all sense of time series trend is lost.
Using the line chart I can fudge the values to add extra null values for a defined list of dates so that the spacing of points is more accurate, but this is only really ok when say there is one point per day and there may be missing days.  If there are sometimes 3 points per day or zero points per day this approach is too cumbersome.
Alternatively I can change the scatter chart to use a line. Anychart has the option to use a line (line_style)  but this isn't included in apex and it cant be added to the XML because it exists within the #DATA# section so the only way would be to fudge the series query to bring that back before the data.
I would have thought that a time series plot would be quite a common requirement - have I missed it somewhere?

Hi thanks for the reply.
I have attached the report I have made. I have written a VBA code to fill in all the details and graphs accordingly. Now the test requirements are as given in the table. I need to specify that in the graph. I dont want the encircled straight line. Just the 2 limits from 10 to 30 ms. In fact the more correct and logical wasy of representing the limits would be 3 horizontal lines, 1 at 10 ms from 22.5-27.5g, 1 at 20 ms from 17.6-22.6g and 1 at 30 ms from 12.5-18.5g.
Hope i have put my doubt across clearly. Again with the code you have given, I dont know how to 'tell' diadem to plot that particular graph in that particular X-Y plot in the report/LPD.
For the 2 lines, this is the code i have written.
'Find 10 ms time
        L3= ChnLength(1)
        L4 = 0
        Do while (L4 < L3)
        L4= L4 + 1
        R1= ChD(L4,1)
          If (R1 > 0.01) Then
                Exit Do
          end if
                 Loop   
        L4= L4 - 1
        LT10=L4
'Find 20 ms time
        Do while (L4 < L3)
        L4= L4 + 1
        R1= ChD(L4,1)
          If (R1 > 0.02) Then
                Exit Do
          end if
                 Loop   
        L4= L4 - 1
 LT20=L4
 LT1 = LT20-LT10
          For i  = 0 to LT1 'Lt1 is var for channel length from 10 ms to 20 ms
            ChD(LT10+i,"Upper limit") = 27.5-(4.9*i/LT1)
          Next
 Thanks again. Waiting for your kind help!
