Has anyone been able to successfully render a cross-hair programatically in Highcharts?
I have a visualization playing an animation through time and I would like to co-relate the position on the chart via the crosshair. I find that visual cue better than selecting the point on a series. Thanks!
Although Highcharts has something called a cross-hair, I guess what I'm looking for is a plot line.
I've found documentation here and an example scenario
EDIT: I've also noticed that marker.enabled must be set to false or the plot line doesn't show.

I got an situation like this. I would like to using line chart to draw stacked value. I have tried google search but i can't find the solution.
For example: On date May/23 i got 3 values, i would like to display these on line-chart.
How could i achieve this? Does highcharts support to do this one. Please take a look at the link attach to clearer the question

I should use scatter-chart to achieve this one
Regarding the tooltip, I would suggest using a scatter series instead of a line. Set the lineWidth in the plotOptions and it will plot just like a line series, but the tool tips are handled differently. Example: jsfiddle.net/jlbriggs/c1o8Lwgv
Does highcharts support phase change lines ? It may be called multiple things but im looking to see if an X axis delineation line can be drawn in highcharts. It is used to specify a specific date in time where something in the environment changed. The chart reader would then look at that line and see if that change to the environment impacted the data represented by the lines in the line chart.
Anyone know if this can be done with high charts ? Sample image attached.
Great answer from Ondkloss: http://www.highcharts.com/docs/chart-concepts/plot-bands-and-plot-lines That page shows exactly what I was looking for.
i like to show additional informations on a highchart graph by clicking on a datapoint. I like to visualise this "clickpoint" by setting a flag. That can be done linke the sun that will be shown here: http://www.highcharts.com/demo/spline-symbols/gray
But i did not find any information in the api how to make this marker clickable. Isnt it possible? In the highstocks API i found clickable flags that can be set. But i need to use the highcharts api only.
Maybe some of you have solved this problem and an give me some hints.
Thanks
You can catch it by click function on the point.
I have a highcharts chart on jsfiddle here: http://jsfiddle.net/hohenheim/j8cTE/15/
The graph does not render when the page loads but when I hover over the area where the chart should be, some bars render.
Here is what it looks like on my screen: http://i.imgur.com/uJ5AtVE.png Is there a way to make the highcharts render on load and to render properly?
Note if you want to see if the data, you can uncomment the alert line.
//alert(JSON.stringify(data2));
Answering my own question: this is a known bug in 4.0.1 of highcharts as per Pawel's comment. Solution is to change up the highcharts references to working versions.
I'm developing an app now with achartengine to draw a line chart. Now I have a problem with an effect that I hope to fix. The effect is, when users touch a point on the line chart the color or style of point can be changed to different color or style. But the other points should remain the same as before.
I was not able to find any function to set a point color or style on achartengine API document.
Can someone please point me to any documentation that can help me with my problem?
There isn't such API available. However, you could create a temporary series that would contain one single point (the selected one), add it only as long as you need it and when no longer needed, just remove it from the dataset.
