I'm currently using ChartFX IE 2000 on our IIS webserver.  I have a chart

that has a list of stages in a process as the X axis data and a number value

for the Y axis. I need the X axis to be split up into several categories of

stages, so I used Annotation line objects to create a line at certain

stages. Therefore, as a simple example, the X axis would look like the

following:

| Stage1 Stage2 Stage3 | Stage4 Stage5 Stage6 | Stage7 Stage8

Stage9 |

I also use text box annotation objects to add more information to each one

of the stage categories that are placed underneath the stage names and

between the lines that separate the stage categories. This has worked Ok in

a way. I use the following code to position the objects. For the stage

category lines, I use:

Category.Attach 1,"5,-90"

where Category is the line annotation object. I am wanting the object to

be attached to the 5th stage, and I have to use -90 so that the lines will

appear below the x-axis. The line object is set with a height of 143 in

order to get the line to take up the room between the x-axis and the top of

the legend box at the bottom of the graph. This in and of itself is strange

because the numbers don't add up. It seems that the line would be drawn

from the -90 value to 143 pixels below that, but it isn't. This sets the

line to start at the x-axis and go down to the legend box. I use the same

method for the text objects that are centered between these lines, again

attached to a certain stage.

My problem occurs when either you zoom in on the graph, when you try to

print the graph, or you resize the graph (not dynamically, but from the

server side before the graph is drawn). The objects are no longer really

attached to the right spot. The lines and text boxes move vertically. If I

understand the attach method correctly, the objects are supposed to remain

attached to the values that I assigned them to, no matter if the user zooms,

scrolls, or prints. But this is not the case. Any suggestions on how to

set these objects permanently to a certain stage value so that they will

always appear in the same place?? I'm sorry I cannot give a good code

example because the information presented by the graph is proprietary. I

appreciate any insight on this problem.

>> Category.Attach 1,"5,-90"

I am afraid zooming will cause trouble because your object is "attached" to

value -90 in the Y axis (probably your min is close to this number) but

zooming affects the Y axis so the object will be moved. Changing the min in

the Y axis will also show a problem because your stage objects will be drawn

inside of the charting area. You may want to try converting values to pixels

(using the ValueToPixel method) so that you do not have to attach. Also note

that if your data is variable, you may need to pass the data first and then

request the Min in the Y axis or set it after passing the data to a known

fixed value (e.g. -100)

I know this may not help you right now but in ChartFX for .NET we can create

multiple X axes and you can create groups so you would get very close to the

chart you are building, maybe now is the time to move to .NET :-)

I understand what you are saying.  I have two questions in regards to what

you mentioned. First, if I set an annotation object to be attached to the 5

data value in the x-axis series (this series is categorical based on stage

name) and to the value of 0 on the y-axis series, then shouldn't the line

object start at the location where the x-axis is?? Whenever I do this, and

keep in mind that the line object has a height of 100, the line is drawn a

little above the x-axis. I'd say about 10 pixels or so, leaving about 90

pixels below the axis. This is using the 'Category.Attach 1,"5,0"

statement. My understand is that the top left corner of the line object

should be attached to the 0 value of the x-axis, no matter if you zoom in or

not, according to the documentation.

My second question is in regards to your suggestion of using the

ValueToPixel method. When you use that method, will the line object stay in

the same 'relative' location when you zoom in on the graph, or does the

object always stay at the given x, y pixel position regardless of the zoom

state??

Thanks.

You mention using the ValueToPixel method.  I can't get it to work at all.

Here's an example of how I use it (assume Chart object already exists):

Dim x, y

Chart.ValueToPixel 40, 0, x, y, AXIS_Y

This always returns an error saying 'Type Mismatch: 'ValueToPixel'". I've

even tried:

Dim x, y

x = CLng(0)

y = CLng(0)

Chart.ValueToPixel 40, 0, x, y, AXIS_Y

But it still produces the same error. How exactly am I suppose to use this

method???

Thanks for your help.
