[User (Legacy)]

How can I display tick marks AF_DATETIME plot for 12AM and 12PM only?

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.

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.

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.

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?

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."
