How can I figure out where I clicked

Submitted by jwcnmr on Fri, 12/05/2008 - 19:29.

I have a chart2d object where I plot 2000 data points with x-values that range from 0 to 5041 and y-values from -800 to +400. When the data are plotted, the x-axis ranges up to more than 5500. So, if I click on the plot and get the x-value of the mouse, how can I convert it to X-axis units. In other words, how can I find the right-most plot value so I can figure out where I clicked?

Chart Axis Labels - Custom Formatting function?

Submitted by matt14m on Fri, 08/29/2008 - 19:36.

Hi there, I'm somewhat new to Dojo and liking it. I have a need to create custom Axis Labels. I'm a aware that I can setup name/value pairs "1" = "one", etc. My y axis is a currency that could range from 0 to millions. Rather than define the points I would like to pass in my data (IE: 150000) and have the label call a formatting function to output ($150,000). The idea comes from the FLOT library under jQuery which I previously used.

Any help would be appreciated if there is a way to do it with the existing code. Otherwise it could be a consideration for upcoming releases.

drawing a vertical line within dojox.charting.Chart2D is it possible??

Submitted by sheadley on Thu, 07/17/2008 - 21:12.

I am trying to create a chart with 2 Series of data. The first series will be a vertical line which will be associated with Time(in days). The second series will be medical data collected for that day, example blood pressure. I have been able to graph the BP readings but unable to do the vertical line for the day. Any help would be appreciated. So far here is the code to display both datasets:


var chart1 = new dojox.charting.Chart2D("test1");
chart1.setTheme(dojox.charting.themes.PlotKit.cyan);
chart1.addPlot("default", {type: "Lines"});

Chart multiple markers

Submitted by darkblue_b on Mon, 07/14/2008 - 16:10.

I have a chart, its working well.. However I have a new challenge. The elements are integers, so its pretty easy to have several markers on the same spot. I use mouseover with a well-formatted tooltip. But now I am looking into differentiating between several markers on the same spot. Any ideas on that?

2-coord data series entry in widget

Submitted by xiangqi on Thu, 07/10/2008 - 21:48.

[editor: moving to the appropriate forum…]

when x-axis is not composed by natural numbers in chart2d,

we can do addseries("Series A", [{x: -0.0375, y: 0.798372056461259},{x: -0.0275, y:0.6633}...]);

how do we do it in widget? both raw entry data=, or htmltable?

also performance-wise, widget seems to be running a lot faster than charts, why so? your advise is greatly appreicated.

Can a Chart2D have a "hole" of data?

Submitted by jl.c on Mon, 06/16/2008 - 14:36.

Hi all!

We would like to use dojox.chart for graphing our monitoring graph, and I'm currently analyzing how we could use it.

Basically, I would like to know if we can have some "hole" of data within a single series in a Chart2D graph.
"hole" mean: no data, so the line can be broken at some point, and continue later on.

ex: 1, 1.5, 2.2, 12.4, -1, -1, -1, 2.3, 5.9, -1, -1, -1, 7.2

Using current chart implementation, all '-1' data won't be graphed, BUT there will be a vertical line between 12.4 and 0, then between 0 and 2.3, and again between 5.9 and 0, and 0 to 7.2.

Chart2D: Error: 'this.rawNode.fill' is null or not an object

Submitted by dojo_user28 on Mon, 11/19/2007 - 22:32.

I have tried to creating Line Chart2D, but randomly I get "Error: 'this.rawNode.fill' is null or not an object".
If I refresh browser(IE6) several times, the error disappears. Not able to find the root cause.

Any idea?
