AxisX and Custom labels question

Recommended Posts

I am trying to customize the labels so to reflect the actual time (DateTime.Now) when they show up on the screen in (RealTimeMode.Scroll, RealTimeAction.Append). In example:

I have 30 points, AxisX.Max = 30, BufferSize = 30, AxisX.MinorStep = 1, AxisX.Step = 3, AxisX.LableValue = x (where x is the number of seconds between the: BeginAddData and EndAddData calls). Let's say x = 1.

What I want to do is: Every lable (MajorTick) on the X axis to show the DateTime.Now + the number of seconds ( x * lableIndex ). I spent a day and couldn't find a flexible way of doing this.

The way i'm passing data to the chart is pretty straightforward: chart.data[x,chart.axisx.count -1] = y once every second.

What I want to do is format the labels like this: DateTime.Now.AddSeconsds(lableX index). So i.e. the next lable that appears on the chart should be DateTime.Now.AddSeconds(26) (because it is the 26th step or major tick)

And there is one more issue, not related to AxisX labels.When I disable all of the commands in the chart:

foreach (Command com in chart1.Commands)

com.Enabled =

false;

There is one command that is still enabled: "Edit title". How can I disable that command and if I do, would that prevent the property box from opening when the end-user right-clicks on the chart. I'm thinking, if all of the commands are disabled, then the property box itself should be disabled right ?

Why would anyone bother to reply to me? Aside those two problems that I have, there's a serious problem that i came across in my application. When using the real time data and constantly appending new values to the chart, when i minimize the chart it blows up with a hard error. All it takes to reproduce it is to minimize and maximize a couple of times. Anyone interested in more details, look at the screen shot and/or send me a message.
