Similar to this QuestionI would like to rotate my x-axis labels 90 degrees. Currently my labels are rotated about 80 degrees with default settings.
Could somebody help me adapt the bar-chart solution for rotating labels, so that I can use it on line-charts? This answer is for chartjs 1. X for an answer covering 2. Using the same method as in the previous answer the only thing that needs to changed is the extension of the graph type.
This time it is extending the line chart and the set-up is a little different as the Line charts scale is created in the build scale so this time it is buildScale is overridden so that the custom scale is used and the new option overrideRotation can be passed in. If you are using chart. It works for me! And if you want to all x-labels, you may want to set autoSkip: false. The following is an example.
Here's a slightly more hackier version Quince's answer is better - the following may break if a future implementation of Chart. The label rotation is calculated by progressively rotating the labels so that they fit between the vertical grid lines - the space between them is calculated using scale. We jump in at the right point to force the result of this calculation to be 0 by making scale. Learn more. Asked 4 years, 2 months ago.

Can anybody point me in the right direction? Also will be nice for an answer for the ABC problems i'm facing. AnghelGabriel I believe this is fixed in If you'd like to give it a try you can sync down the master branch and build using gulp build. What about the other things.
Is there an option for custom paddings? The fix in was not included in v2. There is currently no option for custom padding for the axis title. There might be some ways to fake it out, but I wouldn't recommend investigating them. I tried the fix and it did not solve the problem. So to try to recap.When creating a chart, you want to tell the viewer what data they are viewing.ChartJS Tutorials #3 - Diving Into The Data Object
To do this, you need to label the axis. The scale label configuration is nested under the scale configuration in the scaleLabel key. It defines options for the scale title. Note that this only applies to cartesian axes. It is also common to want to change the tick marks to include information about the data type. To do this, you need to override the ticks. In the following example, every label of the Y axis would be displayed with a dollar sign at the front.
If the callback returns null or undefined the associated grid line will be hidden.

Copy and paste this row onto row 5 in index. After pasting, your head should look like so:. The last thing we need to prepare before we can start visualizing our data is to define an area in our HTML where we want to draw the graph.
For Chart. On row 13 in index. What this ID is set to has no significance for Chart. To draw lines and add labels along axes, Chart. So all we need to do is copy each row in our table above, seperate each value with a comma, and then end and start the list with -brackets.

Copy all of these rows, and paste them into script. At last! Visualizing data with Graph. All we need to do is define what graph we want to draw, and pass in the data that we want to visualize. You created a graph!The radar chart allows a number of properties to be specified for each dataset. These are used to set display properties for a specific dataset.
For example, the colour of a line is generally set this way. All these values, if undefinedfallback first to the dataset options then to the associated elements. If the value is undefinedspanGaps fallback to the associated chart configuration options. The rest of the values fallback to the associated elements. The radar chart defines the following configuration options. These options are merged with the global chart configuration options, Chart. The radar chart supports only a single scale.
The options for this scale are defined in the scale property. The options for this scale are defined in the scale property, which can be referenced from the Linear Radial Axis page.
It is common to want to apply a configuration setting to all created radar charts. The global radar chart settings are stored in Chart. Changing the global options only affects charts created after the change. Existing charts are not changed. The data property of a dataset for a radar chart is specified as an array of numbers.
Each point in the data array corresponds to the label at the same index. For a radar chart, to provide context of what each point means, we include an array of strings that show around each point in the chart.
Radar A radar chart is a way of showing multiple data points and the variation between them. They are often useful for comparing the points of two or more different data sets. No results matching " ".

This is a list of 10 working graphs bar chart, pie chart, line chart, etc. Bar charts are created by setting type to bar to flip the direction of the bars, set type to horizontalBar.
The colors of the bars are set by passing one color to backgroundColor all bars will have the same coloror an array of colors. Line charts are created by setting type to line. By default, lines come with a dark transparent fill, covering the area between the line and x-axis. If you want to remove fills for all your line graphs, a more efficiant way of achieving the same effect is to change the global default for fills: Chart.
Pie charts are created by setting type to pie. They are almost identical to doughnut chartsand will work with the same configurations part from changing the type. Radar charts—also known as web charts, spider charts, star charts—are created by setting type to radar. Radar charts typically require more vertical space than other graphs to be legible, so you might have to tweak the graph proportions.
A polar area chart is created by setting type to polarArea. Polar area charts are closely related to pie charts, with the difference that in addition to the angles representing the relative size of the data points, the radius of each element is set in relation to its value.
Doughnut charts are created by setting type to doughnut. They are almost identical to pie chartsand will work the same configurations. Horizontal bar charts are created by setting type to horizontalBar. They are identical to regular bar charts in every other aspect, and will work with the same configurations.
Setting the color for that group of bars is then done by passing a color to backgroundColor. You can mix several charts and overlay them on top of each other. This is done by setting type to bar not to e. To produce the graph above, for example, we have four data objects: two set to barand two set to linewhile the type for the Chart object is set to bar. Bubble charts can be great for visualizing a lot of different data points simultaneously. In this example, every bubble is made up of three values: x position, y position, and size r —showing the GDP, happiness, and population, respectively, of each country.
