Hello, I would like to know how to "unlink" the X-Axis and the graph.
Basically I would like to do something like this download/file.php?id=122
I have some IMC measures that i'd like to display on a 24h timeline, the trouble is that in the sample files provided, every graph point match exactly an X-Axis point, and this isn't really correct.

For example, I can have 18 measures on 24 hours, and i'd like to display it at the times it were taken, is it possible ?

Sorry for my bad english.

I'm not 100% sure if this is what you need but you could look at this.



$skip_labels = 100;
LabelSkip"=>$skip_labels

thanks, skipLabels is what I needed.
Now I just have to format a little bit my graph but basically it's done, thanks a lot

eeeww, after trying some differents setups, that's not really what I do need :/, let me be more specific.

What I'd like to do basically, is to draw X and Y axis with manually set points (Y axis is ok, but X not yet), and then draw a graphic over it so I can place my points where I want.
The main problem for me it's that I have random measures at random times, and I need to display them on a formatted axis (1 week, 1 month etc...) If i display directly the measures on X-axis, the timeline is scattered and do not flow as the time do.

Is it possible with pCharts to draw a point on the graph without displaying it on the X-axis ?

Hmmm, are you saying if you have an X axis scale for example in seconds like


3
2
1-----*---------------------
0-*-------*-----------------
1---2---3---4---5---6---7---8


you want to put a point (*) on the graph in between the second marks?

Even better is if you can create a sample graph showing what you need, even
if its in Excel, MS Paint, or Word it would help.

Thanks
Lee

Hi lee, thanks a lot for your time,
What you draw is exactly what I want, I need to put some points independently from X axis, like this


So my points can be on axis or not, and with the X axis directly drawn from the addpoint() method it isn't possible

Anything is possible if you mess with the code enough.



But I wouldn't recommend messing with the class code.

But to get serious, I can't think of why you would need to put a data point in between two points in time but you can still make the chart look like it with a combination of changing your addPoints data and using LabelSkip. Beyond that you would have to mess with the pChart source and I'm not sure that's allowed.

Good Luck

that's what I did finally , and that's why I needed to put points between two time points :
Imagine a patient, temperature surveillance for a week or so, the nurse take his temperature randomly (once every 20min, 30min etc...) so if I want to display a week of measures I have to choice :
- display an X axis completely shattered (8h, 8h05, 8h37, 8h59 and so..)
- generate N measures VOID and format my graphic so my axis is like a timeline (8h00, 9h00, 10h00...) and then place my points on "fake" axis hidden by labelskip (I did it like that)

thanks for your help anyway
