I've lost x label of my waveform graph.
My original waveform graph looks like this.
But, for some reasons, x label of the graph was disappeared, like this.
I checked the property of the graph. The x scale property looks like this.
As you can see, x label(time (sec)) is there in x scale property, and then the 'Show scale label check box' is checked, but not displayed on GUI.
Where is the label? How to display it again?
I had exactly the same problem. Apparrently one can make the x-label visible again by right-clicking on the indicator --> Advanced --> Reset Scale Layout
Not sure what happened here, unless you share this control (may be copy it on a blank VI and share across).
However You can try following to check if you are able to see the label for x-axis:
a. right click the graph indicator and select ADVANCE >> CUSTOMIZE.
b. Now press 'ctrl+M' to switch to 'Customize Mode'.
c. Now check if you can find the x-axis label.
The easiest way to get this resolved, is by replacing the existing graph by right clicking on it.
Right click your graph on the front panel, highlight 'X Scale' and make sure 'Visible Scale Label' is selected.

I have an XY Graph in Labview. I have no problems with its basic functionality.
I'd like to have a marker on the plot (independent on the cursor) which would stay in a certain position that I could read out and display in the GUI. Also I want the user to be able to move the marker to a new position.
How can I implement this functionality?
I know the title isn't very well-chosen, so I'll be grateful for any edits.
Edited:
You can just add cursor.
Add a cursor, select the point style you like and click on Allow dragging as shown on the picture below.
You can modify or read the current position of the point using Cursor Position property of the XY Graph.
They’re called “annotations”; you can add an array of them via a property node.
When calling axis.setExtremes() or axis.zoom(), the associated zoom button does not become highlighted.
For example, if I programatically 'zoom' to 1-hour, I would like the '1 hour' zoom button to appear as 'pressed'.
Is there a simple way to accomplish this?
For more context: I want to make my app stately, so that if you view a graph, zoom, then navigate away from the graph and back to it again, I want to restore your 'zoom level'.
I have this basically working by listening for afterSetExtremes and storing the max/min values, and then using those to call 'zoom' on the graph when the user returns.
If there is a simpler way to accomplish this, I'd be fine with that.
Thanks for any direction!
You can also call setState on the button.

chart.rangeSelector.buttons[3].setState(2);
I am working on line chart in flex. I have to show the tooltip data on the datapoint itself. Normally the data point value is displayed on a rectangular area when we mouse over on the data-point. But I have a checkbox just below the chart. When I check on it, all the datapoints of the graph should display the value on data-point on the graph. Any idea how to do that?
In your mx:LineChart control set the showAllDataTips value to true/false according to your checkbox.
After doing a few research I found the answer. My goal was to draw something on the datapoint itself. I found this link useful Drawing on chart controls EDIT : new link
Going through this link helped me a lot.
I assume I need to override the mouse over and mouse off event so that they don't do anything and then trigger the mouse over event for each column on the graph.
Anybody got any suggestions?
What you are looking for is the property showAllDataTips for the chart to true.
This will force all the available dataTips on the chart to become visible.
I guess this should do what you are trying to get done.
The mouseover event for the graph seems a long shot but its still feasible incase you want to show data tips on some kind of interaction.
But I would suggest on mouse rollover , change showAddDataTips= true and on rollOut showAllDataTips=false .
That should do the trick.
You probably want to use data labels:
By default, BarSeries, ColumnSeries, and PieSeries objects do not
display data labels.
To enable data labels on BarSeries and
ColumnSeries objects, set the value of the labelPosition property
to inside or outside.
To enabled data labels on PieSeries, set the value of the
labelPosition property to inside, outside, callout, or
insideWithCallout.
Cheers!
I have a single series bar chart created programmatically in codebehind which I would like to display the Y point value (somewhere above the bar, or maybe as a tooltip) when the user hovers their mouse over a bar.
Is there a native onmouseover event for the bars of the chart, or is it something that should be added through series.MapAreaAttributes?
Thanks!
Edit
After some experimenting I've found the points.tooltip attribute which I can add at the same time I add the point which will do what I want it to do, but it would still be nice to know if you can capture events for the bars, just for future reference.
From Show all series' values in stacked bars mouseover (ASP.NET CHART)
series.MapAreaAttributes = "onmouseover=""showTooltip('#VALY');"""
Where your showTooltip function would do as you required.
