Zoomline Charts

[Leo]

I have a problem with the ZoomLine charts. Hopefully I am not missing something.

 

My datasets are of 5min log data. I have set my categories to be 5 mins.

 

When the chart initially displays it appears to be picking an 25min time value to display the values along the x-axis. It would be useful to be make these 15 or 30 min intervals.

when it displays the data itself it is either averaging the values and displaying that or taking the actual values at those 25min intervals and ignoring other values inbetween.

 

The problem with this is that before you zoom in it appears that there is a max value of say 100 yet when you zoom in it shows that there is an actually a max value of say 200. So the initial view of the graph is misrepresenting the data to be displayed.

 

What I think should be possible is :

- to be able to chose the number of intervals to display on the x-axis and which label's to appear as you do on the normal 2D line chart

- display all datapoints on the initial chart regardless of the x-axis labels.

 

Cheers!

Hey Leo,

 

Please find my responses to your requirement here below.

 

- to be able to chose the number of intervals to display on the x-axis and which label's to appear as you do on the normal 2D line chart

>>> You may use the 'numVisiblePlot' attribute to control how many data plots would appear in the visible area of the scroll pane. You may also use the 'numVisibleLabels' attribute to set the number of data labels that are to be visible in one screen.

 

In case, you would require to set the extreme left (first) data point and the extreme right (last) data point, you may use the 'displayStartIndex' and 'displayEndIndex' for the same.

 

Details on these attributes can be found at:

- display all data points on the initial chart regardless of the x-axis labels.

>>> Please my response to the query/functional requisition above. Furthermore, it would not be visually or functionally feasible to plot thousands of data points on the Zoom Line chart. Visually speaking, it would be a very a very messy and unstructured end-visual. Functionally speaking, the Zoom Line chart is able to plot thousands of data point using it's Zoom function. Without the same, it would not be possible due to the Flash players unique limitations.

 

I hope I have been able to justify on these points here. Please feel free to carry on discussion on this topic.

Hi,

I am using numVisiblePlot and trying to achieve that I could show only 20 visible plots on the chart and the rest would be accesible by scrolling right. And that does not work. Am I doing something wrong?
