I am using the default Highcharts single series stock chart: http://www.highcharts.com/stock/demo.
I am trying to hide the "From" and "To" label from the date range input boxes up top right. I then want to insert a "-" between the two input fields.
I am hiding the "From" and "To" labels by:
labelStyle: {
display: 'none'
},
This removes the labels (and also the Zoom label, which is fine for my exercise) but the space reserved for the labels still exists. How do I go about removing the space reserved for these labels and pushing the two input fields closer together and inserting a "-" between them?
jsfiddle: http://jsfiddle.net/rlsaj/b9sfeLpg/
You can edit the label values by using the rangeSelectorFrom and rangeSelectorTo properties from the language settings. But to be honest I don't know if this affects the consumed space between the inputs.
See: http://api.highcharts.com/highstock#lang.rangeSelectorFrom
Unfortunately it is not available, so you can post your suggestion here

Is there a way to force a timeline series' dataLabels all to one side or the other?
I have a vertical timeline in Highcharts with several series (shown with "alternate: false"):
I would like to have, for instance, all of the "Sent for execution" labels on the left side. The "alternate" option moves some of them, but not all.
Okay, I found the answer while asking the question.
Set the "distance" option to a negative value with "alternate" as false. Here it is set to -100.
In Vaadin 14.4.2, is it possible to create a Chart with multiple series in a way in which the color of the series is programmatically calculated? Specifically, I may have ~100 series, but they all are associated with a "number" (specifically a mass of a chemical element). Since I know what in my application the "number" (ie the mass) will range from 100 to 2000, I would like the color of the series to range from blue (at 100) to red (at 2000). This way, when a user looks at the graph, they intuitively know whether the series refers to a heavy chemical (red) or a light one (blue).
In order to accomplish this, I think I would need to have some way of programmatically setting the color of a series, but I do not think that's actually possible in Vaading 14.4.2, right?
Here's an example of such a chart:
Color of the data series are defined by the custom properties --vaadin-charts-color-0, --vaadin-charts-color-1, ... , --vaadin-charts-color-9. You can programmatically define their values like follows
charts.getElement().getStyle().set("vaadin-charts-color-1","#2dd7a4");
The second string parameter is the color value, it can be any format accepted in CSS.
Is there a way to order the column display in order to force the columns with smallest values forward (higher z-index)?
Here's a non-grouped column chart, which is accomplished by setting the grouping: false in the column settings for the plotOptions.
The idea is to always have the smaller bar on top (if there are multiple bars, continue stacking the taller ones behind). Notice this example uses transparency to circumvent that issue; however, the new color is not reflected in the legend.
I've scoured the Highcharts API but couldn't find much information.
In order to do what you're asking, you would have to set a z-index value for each data point in each series (similar to how you can set a unique color for each data point, such as data: { y: 10, color: 'blue' }).
Unfortunately, the Highcharts API doesn't recognize z-index values for individual data points. Different z-index values can only be applied at the series level.
You may want to consider translucent columns with different widths, as shown in the "fixed placement columns" demo: http://www.highcharts.com/demo/column-placement
I hope this information is helpful for you.
I'm in the process of evaluating Highcharts as a replacement for our current platform, and have some questions about how we can replicate one of our existing charts:
I've been able to recreate the basic floating stacked column chart, but need help with some of our specific features.
1) Is is possible to replicate the multiple y-axes with the columns displayed to the right of each within a single chart? If not, I suppose we could do 3 charts next to one another - and draw our own titles above (and data table below). If we go this route, is there a way to group all these elements in a single "container"? We need to export these charts to images and need to end up with a single image that looks like the one attached.
2) How would I create the inner box within each column? Do I need to draw it myself, or can I create another column series with a border and transparent fill and somehow set the width of the column to be less than the width of the main columns (note that the number of columns on each chart is dynamic, so the column widths can't be a fixed size. i.e. the inner box width needs to be a percentage of the main column width)?
3) Assuming #2 is possible, I could probably use the same technique to plot the horizontal line - just make the height 0 (or very small) and make the bar wider instead of smaller. Is there a better way?
4) How do I get the x coordinates of the columns so we can align our data table under each column?
5) Can I separate the individual points within the column. You'll notice in my jsfiddle, product 1 and product 2 are vertically aligned in the center of the column. Can I spread them out within each column as the 2 points are in the screenshot?
Thanks in advance for advice on all or any of the above.

1) You can use multiple yAxis, see the example
2) You can use renderer or mix column/column range and border parameter, example
plotOptions: {
columnrange: {
pointPadding:0.2,
color: 'rgba(255,255,255,0)',
borderColor: '#303030'
}
},
3) Use renderer, as above or scatter series with customied marker
4) Column is shape in point.element.graphic, so you can extract it.
5) as far as I know, it is not possible
I have a situation where I need to remove all margins from a highchart and remove the x/y axis so it fills a series of columns in a table completely.
I did that, no problem. Chart goes to the extremes as needed.
What I need now is that pesky yaxis I already removed...but displayed in a table cell outside of the existing highcharts object.
It would seem easy, as though I could just set the overflow property of yaxis to 'visible' and play with the offset...which would work however this would only work if I wanted to re-position the axis within the boundaries of the highchart object. I want him in a different cell entirely.
Is there anyone who has had experience in this situation? Is it going to require me to have a secondary highchart with only a y-axis?
Best answer gets a green check.
EDIT :: I now have dispersed each 'day' into their own column (more bars coming per day [scheduled,actual,etc...]). In order to keep the scales lined up, I manipulate the yAxis:max property and set them all to a derived value.
In the open column (currently w/ text Hourly Trends) is where I would put an additional highchart module with no series data but with the same min/max/tickInterval.
The next big leap will be to see the data is alive and changes w/ schedule. May have to start another thread for that one, no?
Create a new HC object with no data but only the yAxis (making sure it is the right scale, etc). Perhaps add the same series of data to it but hide the series? Add it to the location you want. This seems kludge and not very good practice. Each business use is different but why would you want this?
EDIT based on comment of business rules:
Why not come at this from a different direction and have the individual chart elements (the bars/points/etc) be a single point chart. This way you have one chart per column. You can then set up the yAxis to be text and not worry about the position. If we could see an example of the page layout and the desired result that would help.
