Frequently Asked Questions.

The installer says that Coldfusion Studio isn't detected and won't install. I am running Coldfusion 4.5.
Due to a bug in the installer, it couldn't detect the presence of Coldfusion Studio 4.5. There is now a new version available to download. Just click here to go to the download page. Just enter the serial number you have been issued and you will be able to download the latest version.


Does CFXGraphicsServer have support for horizontal line graphs?
At present there is no support for horizontal line graphs in CFXGraphicsServer.


How do I specify the font sizes?
When specifying font sizes in CFXGraphicsServer, you can either specify the maximum font size to use in positive integers, or force the font to a given size (even if it would cause the text to overlap with other items) by using a negative number.
So, for example:
If you set a font to size 100, then the text will be displayed at size 100 or smaller, depending on whether it will fit.
On the other hand, if the font size is set to -100, it will force the text to size 100, even if it does not fit. This can be useful if legibility is an issue with a particular graph.


Can I display a graph that uses data from multiple data sources?
You can supply a CFXGraphicsServer tag with one query from which it takes it's data. You can, of course, use SQL in ColdFusion to amalgamate data from multiple sources into a single query.


The XAxisMin / XAxismax attributes don't appear to work properly.
If you find that XAxisMin and XAxisMax attributes do not seem to be working, this is probably because you have not set the XAxisStyle attribute to 2 ("user-defined"). This tells CFXGraphicsServer to use the user-defined axis extremes rather than determine then from the graph data.


The YAxisMin, YAxisMax and YAxisTicks attributes to not appear to work
In order to use the above three attributes, you must set YAxisStyle="2", this instructs CFXGraphicsServer to use user-defined y-axis bounds. You then need to ensure that YAxisTicks is set high enough to provide the granularity along the Y-Axis to display the values of YAxisMin and YAxisMax.


How do I remove the URL at the bottom of the graph?
An early feature of our product was a link back to our support unit. Many clients have asked us to remove this- the code will be changed in later releases.

Please use the following 'work-around' to achieve the desired effect in the mean time.

In the "HKEY_LOCAL_MACHINE \ SOFTWARE \ IVision \ CFX_GS" registry key add a string value called "authorise" (NOTE: UK spelling of "authorise") and give it the value "AppleJack" (NOTE: Uppercase A,J; rest in Lowercase).


How do I only display a label on some of the tick marks on the graph axis?
Use the tag property "LabelEvery".
Set this value to the frequency of the labels that you wish to have.
For example, if you are displaying values over a range of 60 minutes, but you only want a label on every 5th minute, you should set LabelEvery="5".


How do I only plot a tick on the axis at certain intervals, and not for every point plotted?
If the number of tick marks being drawn on the graph is too great, you may need to display less of them to make the graph more clear.
To do this, you must set the following attributes:

• XAxisStyle="2"
• Ticks = whatever tick style you want (0 or 1 or 2)
• XAxisTicks = number of ticks you want for the given range (ie. XaxisMax minus XAxisMin)
• XAxisMin = min value on the x-axis
• XAxisMax = max value on the x-axis
• st_dataset = values of points to be plotted
• st_xposset = corresponding x-value of each point in st_dataset (ie. should increment uniformly for your data)
