Software FX Posted April 26, 2004 Report Share Posted April 26, 2004 Can you please explain. How is your data, do you have string labels, x-values, ? We need more information than this in order to be able to point you in the right direction. -- FP Software FX Link to comment Share on other sites More sharing options...
User (Legacy) Posted April 26, 2004 Author Report Share Posted April 26, 2004 I am using date/time x-values. Some days I may have 24 points to plot and other days may be several more. I need to only show tick marks for the top-of-the hour (ex: 1:00 AM, 2:00 AM). Let me know if you need more information.

Software FX Posted April 27, 2004 Report Share Posted April 27, 2004 If you are using an X/Y chart the number of values will not affect the axis. Simply set: chart.Axis(AXIS_X).Step = 1/24.0 ' One Hour Make sure you adjust your X-Axis Min and Max to also be at the top of the hour. -- FP Software FX Link to comment Share on other sites More sharing options...
User (Legacy) Posted April 28, 2004 Author Report Share Posted April 28, 2004 My problem is that I might have 24 points one day and 10000 points the next day. When the number of points changes, the X scaling changes. I want the graph to look the same regardless of how many points are being plotted. What am I doing wrong? Any examples that might help me?

Software FX Posted April 28, 2004 Report Share Posted April 28, 2004 If you have x-values (as you said you did) the number of points WILL NOT affect the layout of the X-Axis. The scale will. I explained this in a previous posting to you: "What you want is an X/Y charts. The X-Axis then will be independent of the number of points and will simply be scaled according to Min and Max, much like the Y-Axis. There is samples of X/Y charts in the programmer's guide and Resource Center. You wan your Date/Time to be your X-Values. Note that only certain type of charts like Line, Scatter and Area support a true X-Axis, Bar,Gantt and others support only a categorical axis making the number of points have a direct effect over where the points are displayed. For example a bar chart will always displayed bar i right next to bar i-1 regardless of X-Values. X-Values in bar charts are only used for labeling (Data-Driven labels). You can read more on this in the topic "Data-Driven Labels" in the programmer's guide." later ... "I think my answer was in the right direction. You do seem to need an X/Y chart (X values are times and Y-Values are temperatures). Depending on where this data is being acquired from (data base, text file, xml file, data arrays), the code will vary, take a look in the docs on "Passing Data". In particular there is a topic under "Programmer's guide -> Gallery Types" titled "XY Plots & Scatter" that shows you how to pass the data to an X/Y chart. You will then need to set the X-Axis format to be Time (chart.AxisX.LabelsFormat.Format = AxisFormat.Time) and customize further as you need."
