Hi
I have a line chart. I don't to show the line that start in the point (0,0) to the point (x,y)
The point (0,0) is the first point
The point (x,y) is the second point
I want to show the line chart since the second point to the end point |

Hi Nadia,
If you do not want to plot the (0, 0) point, please do not include the (0, 0) in your data. You may remove it from your data before passing the data to ChartDirector.
If you must include a first point in your data, but does not want to plot it, please include a NoValue point, not a (0, 0) point. For example, (NoValue, NoValue), or (0, NoValue).
Hope this can help.
Regards

Hi Nadia,
The (0, 0) point is in the chart because your data contains the (0, 0) point. To remove it from your chart, please remove the (0, 0) point from your data.
If you think there is no (0, 0) point in your data, may be there is a bug in your code that creates the (0, 0) point.
For example, to create a chart with 12 points, some people will use:
ReDim myData(12)
myData(1) = ....
myData(2) = ....
myData(12) = ....
The above has a bug. The myData(0) is not used. (VBScript array starts from 0.) According to VBScript syntax, unused array elements are equivalent to 0 in numeric context. So the myData contains a 0 point as the first point. ChartDirector will accurately plot the myData array and start the first point at 0.
If the above still does not solve the problem, would you mind to inform me of your charting code?

Hi
my code is:
redim data(17)
redim labels(17)
data(1) = a
data(2) = b
.
.
.
data(17)= n
If start in data(0) = a
The line chart start in (0,a)
If start in data(1) = a
The line chart start in (1,a) but begin with the point (0,0)
How do you do to remove the point(0,0) |

Hi Nadia,
Your data should be:
redim data(16)
redim labels(16)
data(0) = a
data(1) = b
....
data(16)= n
labels(0) = "xxx"
labels(1) = "yyy"
....
labels(16) = "ppp"
If you want to leave a gap between the first point of the line and the y-axis. The code is:
Call c.xAxis().setMargin(0, 15)
Hope this can help.
