I am using highstock for scrollbar in highcharts. It is working fine, but when I move scroll forward first of last column of chart hides from chart window. I want to show minimum 3 columns at any point of time. I have used min : 0 and max : 2 in chart configuration.
Here is fiddle for the issue jsfiddle
If category is not full in visible area then column will not be visible either.
If you want to show minimum 3 columns at any time then you could increase max by 1.
Example: http://jsfiddle.net/dum6m6mq/7/
xAxis : {
min : 0,
max : 3,

I'm making a milestone comparison chart, and I'm putting the data labels above the milestone markers. The data labels are two rows of text.
I'm setting my own calculated chart.height in order to increase the row height so I can fit the data labels nicely within each row, and I'm using a combination of series.point.graphic.translate() and series.datalabels.y in order to position everything vertically within the row where I want it. I've got everything almost dialed in exactly how I want it.
However, it seems as though the data labels for the first row of data are not respecting the y offset I'm trying to set. In fact, it looks to me like instead of starting at the center of the row and offsetting the amount specified by series.datalabels.y, there's actually more offset being applied that is forcing the data labels to push up to the very top of the plot area.
In the screenshot, the red lines near most of the milestone markers/labels show what the offset should be: something very minimal, the label should be just barely above the point of the milestone marker. But the red boxes in the top row show how that offset is too much, the labels are being pushed too high (to where the top of the label is right against the edge of the plot area):
What's going on there, and how can I fix it?

Well, I figured it out...
If I just don't apply the y offset to the datalabels for the first row, they seem to line up much better:
// yValue is essentially the row here, so 0 is the first row
series: {
dataLabels: {
y: yValue === 0 ? 0 : -31
}
}

In amCharts 4 column chart, labels on category axis are alternately hidden when user reduces the browser width.
By default the chart automatically hides labels to improve readability. I want to disable it.
Please refer ruining ex. codepen.io/Mishra-Praveen/pen/MWwmVbp
I am getting solution for Amchart 3 not for Amchart4.
categoryAxis.renderer.minGridDistance = 30;
Increasing these numbers will mean likely sparser grid lines and related labels. Decreasing will probably result in denser grid/labels.
In below picture,
The date displayed at end of axis line (x-axis) is diff from date displayed at end of data zoom.
Required,
The date should be same, at axis line & data zoom, When no zoom is applied.
The date should be the last value in data that is passed to charts by settings.

Actually, the chart does show data up to 2009/10/18, but since the xAxis ticks aren't equally spaced, there's a small area at the chart's end
Look what happens when I hover over the chart's right end. It does show you 2009/10/18.
Because the axis ticks are alligned from the left, and the chart's axis is dynamic (because of the custom zoom range), it may not always fit perfectly.
You can, however, play a little with the ticks and labels.
For example, when you have 100 datapoints, you can change the tick interval and label from auto to, let's say, 10 (or another whole number divisible by the number of datapoints).
xAxis: [
{
axisTick: {
interval: 10
},
axisLabel: {
interval: 10
},
}
]
I am using Highcharts area graph.
The type of the chart is "datetime".
The X-Axis labels get well adjusted as long as
Either the width of the chart container div is less than 900px
Or the width is not specified for the div
When I set the width of the container of the div more than 900px, either the labels are appended with the dots or get overlapped.
How it can be resolved. Thanks in advance for any suggestion or help.
You can add the tickInterval option to the x-Axis. This option determines the distance between the individual ticks. For example setting it to
tickInterval: 24*3600*1000
which resembles on day in milliseconds yields no overlapping labels for your chart:

You can also use a new option provided below by highcharts if you are comfortable with showing the labels in 2 or more lines and if you do not want rotated labels.
staggerLines: 2

What is the default width of each column in the DHTMLX bar chart.
I know that we can set the width of bar. But what is the default width of each column.
As I observed it depends on the total width of the chart. The larger the width of the chart, the larger the width of each column in width. Am I correct?
If I am correct with the above statement, in my chart I giving the day number of the months as the X-axis values. the chart is drawing fine till the last day. For the last day I am getting too much space.
Please observe the space between 31 and 1.
Could you please tell me what would be the problem?
How can I get the uniform column width in my chart? Please advice
Chart counts default width itself. It depens on common chart width (container dimention), items quantity, etc.
There is offset settings you can set empty fields "around" chart scale
