To display only a limited part of data in chart.js, you can use the chart.js slice()
method in combination with the labels
and data
arrays of your chart data.
Here is an example:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 |
// Assuming you have an array of full data let fullData = [15, 20, 30, 25, 35, 40, 45, 50, 55, 60]; // Define the number of data points you want to display let displayDataLimit = 5; // Slice the data array to get the limited data points let limitedData = fullData.slice(0, displayDataLimit); // Similarly, if you have corresponding labels for your data points let fullLabels = ['Label 1', 'Label 2', 'Label 3', 'Label 4', 'Label 5', 'Label 6', 'Label 7', 'Label 8', 'Label 9', 'Label 10']; // Slice the labels array to get the limited labels let limitedLabels = fullLabels.slice(0, displayDataLimit); // Set up your chart configuration and options let chartConfig = { type: 'bar', data: { labels: limitedLabels, datasets: [{ label: 'Limited Data', data: limitedData, backgroundColor: 'rgba(0, 123, 255, 0.8)', }] }, options: { // ... other chart options } }; // Create the chart instance let myChart = new Chart(ctx, chartConfig); |
In the example above, the slice()
method is used to extract the first 5 data points from the fullData
array and store them in the limitedData
array. Similarly, it slices the first 5 labels from the fullLabels
array and stores them in limitedLabels
. These limited arrays are then used in the chart configuration to display only the limited part of the data in your chart.
