Intro

A line chart is a basic type of chart used in many fields. It displays information as a series of data points connected by a line. The chart is often used to visualize a trend over time.

The line micro chart supports up to three lines, but we recommend using only one. You can modify the color of each line using the qualitative color palette or semantic patterns for charts.

Usage

Use the line micro chart if:

The line micro chart can be embedded into a tablelisttileor header.

  • You want to visualize the shape.

Use this option to show a trend or sparkline. By default, the chart is rendered in blue, but application developers can set any color for the chart using the names for semantic palette or names from the qualitative palette.

  • You want to show data points that are above or below a certain threshold.

In addition to data points, you can use two different colors for the lines. When the micro chart displays only one line, we recommend that you use only semantic colors, such as green for values above the threshold, and red for values below the threshold. When two or three lines are displayed, on the other hand, we recommended that you use one color per line to ensure clarity and avoid visual clutter. Note that the threshold can also be set to zero.

  • You want to show focus points.

Use this option to display a trend or sparkline to focus on several special values, such as the first and/or last value of the chart. By default, the chart is rendered in blue, but application developers can choose another color for the chart line and data points from the qualitative palette. Note that the threshold can also be set to zero.

  • You want to show focus points with semantic colours.

Use this option to display a trend or sparkline to focus on several special values with a semantic meaning, such as the first and/or last value above or below a certain threshold. Note that the threshold can also be set to zero.

Do not use the line micro chart if:

  • You have scenarios that do not depict time periods.
  • You need to show more than three lines.

Responsiveness and Adaptiveness

The Line micro chart is fully responsive. The size adjusts dynamically based on the dimensions of the parent container. In addition, there are also four fixed sizes – L, M, S and XS. Each fixed size is a snapshot of the fully responsive micro chart for specific dimensions.

You can use the smallest XS size to embed the line micro chart in table cells of the grid tableanalytical table, or tree table (also in condensed mode). When displayed in a table cell, the line micro chart should be left-aligned.

Maximum and Minimum Sizes

The line micro chart can have the following dimensions:

Width Height
Maximum 320 px 94 px
Minimum 64 px 18 px

If the height of the chart is less than 56 px, the labels are hidden.

Layout

Line Micro Chart in a Tile or Facet

You can embed the line microchart with all its features in a tile or header facet. The chart uses the full height and width of the control.

Note: If the threshold is not zero, the title of the tile or header facet should clearly express the value of the threshold (for example, “Values above/below 50”).

Line Micro Chart in a Table or List

You can embed a line micro chart with all its features in a table or list.

Note: If you intend to synchronize the chart visualization, use the manual scale.

Components

To present the line micro chart in the most useful way, application developers can set several properties.

Data points

The line micro chart can display or hide data points. To display data points, we recommend that you use 4 (for quarters) to 12 (for months) data points per chart. The responsive behaviour of the chart hides data points if there is not enough space to display them (for XS size and smaller).

Data points with a semantic meaning can use colors defined by the semantic color palette (green, orange, or red).

If data points do not have a semantic meaning, the line is colored blue by default, but application developers can assign any color from the qualitative palette.

Alternatively, you can show a line-only chart, with all the data points hidden. In this case, you can use up to two colorper line in the chart. If the values relate to a threshold, we recommend using semantic colors for the line to highlight values above or below the threshold.

Focus points

Unlike data points, focus points highlight specific values, such as the first and/or last value of a time series. Neutral focus points are coloured blue. Focus points with a semantic meaning can be colored using the semantic colors (green, orange, or red). The responsive behaviour of the chart hides focus points if there is not enough space to display them (for XS size and smaller).

Threshold

You can set a threshold line. If the threshold isn’t zero, include its value in the title of the tile, header facet, or column in lists and tables to ensure that the chart is not misleading for the user.

There is also an optional threshold value label. The threshold value is hidden if it takes more than 50% of the chart’s parent container. The threshold value is shown only when the threshold line is displayed.

Labels

The labels for the line micro chart are optional. Use the bottom labels to indicate the beginning and the end of the time period. Use the top labels to show the corresponding values for the beginning and the end of the chart. When the chart includes more lines, the smallest values appear in the beginning and the largest values at the end of the chart (across lines). The responsive behaviour of the chart hides labels if there is not enough space to display them (for XS size and smaller or if If the chart height is less than 56 px). Ensure that the labels for the values are not truncated.
