I have a line graph that I need the Y-axis labels to be displayed as integers than floats, as my data has no floats added to it, you should enable an option to set display as floats or integers.

I had this issue but I'm just precalculating the ticks in code PHP before passing the data off to chartjs. After some more testing I found the initial patch caused an infinite loop when using data sets containing zero values. I've just add Math. I have charts with highly variable values. Ahh okay, nice! Was this issue ever fixed in the master Chart.

I'm using the latest version, but I'm still having this issue with decimal numbers on the axis labels. I would imagine this issue must effect a high percent of users who want to us Chart. Here is a function that also does the work to calculate the max value based on MardyGit's code I think it may have been fixed? It's been 6 years and this is still a valid issue : why was it closed? If your data only has small integers I believe less than 10 per data point then it will display floats instead of integers in the axis.

I will also update this answer and add this information. Hopeless this might be what you are looking for: chartjs.

Featured on Meta.The linear scale is used to chart numerical data. As the name suggests, linear interpolation is used to determine where a value lies in relation the center of the axis. The axis has configuration properties for ticks, angle lines line that appear in a radar chart outward from the centerpointLabels labels around the edge in a radar chart. The following sections define each of the properties in those sections. The following options are provided by the linear scale.

They are all located in the ticks sub options. The common tick configuration options are supported by this axis. Given the number of axis range settings, it is important to understand how they all interact with each other. The suggestedMax and suggestedMin settings only change the data values that are used to scale the axis. These are useful for extending the range of the axis while maintaining the auto fit behaviour.

In this example, the largest positive value is 50, but the data maximum is expanded out to However, because the lowest data value is below the suggestedMin setting, it is ignored. When these are set, some data points may not be visible. If set, the scale ticks will be enumerated by multiple of stepSizehaving one tick per increment. If not set, the ticks are labeled automatically using the nice numbers algorithm.

This example sets up a chart with a y axis that creates ticks at 0, 0. The following options are used to configure angled lines that radiate from the center of the chart to the point labels.

They can be found in the angleLines sub options. The following options are used to configure the point labels that are shown on the perimeter of the scale. They can be found in the pointLabels sub options. Linear Radial Axis The linear scale is used to chart numerical data.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 " ". Cap style of the line. See MDN. Length and spacing of dashes. Offset for line dashes. Line joint style. If true, lines will be drawn between points with no or null data.

If false, points with NaN data will create a break in the line.The linear scale is use to chart numerical data. It can be placed on either the x or y axis.

The scatter chart type automatically configures a line chart to use one of these scales for the x axis.

As the name suggests, linear interpolation is used to determine where a value lies on the axis. The following options are provided by the linear scale. They are all located in the ticks sub options. These options extend the common tick configuration. Given the number of axis range settings, it is important to understand how they all interact with each other.

User defined minimum number for the scale, overrides minimum value from data.When it comes to changing the chart size based on the window size, a major limitation is that the canvas render size canvas. Furthermore, these sizes are independent from each other and thus the canvas render size does not adjust automatically based on the display size, making the rendering inaccurate. Detecting when the canvas size changes can not be done directly from the canvas element.

However, this method requires the container to be relatively positioned and dedicated to the chart canvas only. Responsiveness can then be achieved by setting relative values for the container size example :. Note that in order for the above code to correctly resize the chart height, the maintainAspectRatio option must also be set to false. CSS media queries allow changing styles when printing a page. The CSS applied from these media queries may cause charts to need to resize.

However, the resize won't happen automatically. To support resizing charts when printing, one needs to hook the onbeforeprint event and manually trigger resizing of each chart. Responsive Charts When it comes to changing the chart size based on the window size, a major limitation is that the canvas render size canvas.
