User (Legacy) Posted September 14, 2006 Report Share Posted September 14, 2006 Hi Our trend creates peaks in the linechart at the beginning and the end of the trend. I added a jpeg in my poste for demonstration. The chart get the data from a dataset, these values are correct and not responsible for this peaks. This happend in every line chart in our project when there is a change from a big value(eg. 60155) to a small value(eg. 125). I think there is something wrong in the drawing of the chart. Thanks for your help. Daniel Winkler Link to comment Share on other sites More sharing options...
Software FX Posted September 14, 2006 Report Share Posted September 14, 2006 1) What type of Chart is this ? A line chart or a Curve Chart If it is a curve chart this may be caused by the algorithm trying to smooth out sudden changes. 2) Please attach the data for this chart. -- Francisco Padron www.chartfx.com Link to comment Share on other sites More sharing options...

Software FX Posted November 3, 2006 Report Share Posted November 3, 2006 > what do you mean with smooth out? A curve chart is by definition "smooth" meaning that if there is a sudden change in direction, the curve will be extended to be able to make the transition look smooth. Think about it as a car trying to make a sharp turn at high speed, you need to go to the outside of the road in order to make the turn. If you are going too fast or the curve is too sharp, you will need to go out of the road. This is what happens with curve chart, sometimes the transition is so sharp that in order to make it smooth you have to go out of the chart area. A line chart doesn´t have this problem as it just connects points using straight lines. > what do you mean with attach the data, should i poste all the values or > the chw file? how can i get this chw file, where are they stored? The CHW file can be obtained by calling the Export method (Chart class). -- Francisco Padron www.chartfx.com Link to comment Share on other sites More sharing options...
