Tools

generate_area_chart

Generate a area chart to show data trends under continuous independent variables and observe the overall data trend, such as, displacement = velocity (average or instantaneous) × time: s = v × t. If the x-axis is time (t) and the y-axis is velocity (v) at each moment, an area chart allows you to observe the trend of velocity over time and infer the distance traveled by the area's size.

Parameters:

• data (array of object, required): Data for area chart, it should be an array of objects, each object contains a time field and a value field, such as, [{ time: '2015', value: 23 }, { time: '2016', value: 32 }], when stacking is needed for area, the data should contain a group field, such as, [{ time: '2015', value: 23, group: 'A' }, { time: '2015', value: 32, group: 'B' }].
• data[].time (string, required):
• data[].value (number, required):
• data[].group (string, optional):
• stack (boolean, optional): Whether stacking is enabled. When enabled, area charts require a 'group' field in the data.
• style (object, optional): Style configuration for the chart with a JSON object, optional.
• style.backgroundColor (string, optional): Background color of the chart, such as, '#fff'.
• style.palette (array of string, optional): Color palette for the chart, it is a collection of colors.
• style.texture (string, optional): Set the texture for the chart, optional, default is 'default'. 'rough' refers to hand-drawn style. Values: default, rough
• style.lineWidth (number, optional): Line width for the lines of chart, such as 4.
• theme (string, optional): Set the theme for the chart, optional, default is 'default'. Values: default, academy, dark
• width (number, optional): Set the width of chart, default is 600.
• height (number, optional): Set the height of chart, default is 400.
• title (string, optional): Set the title of chart.
• axisXTitle (string, optional): Set the x-axis title of chart.
• axisYTitle (string, optional): Set the y-axis title of chart.

generate_bar_chart

Generate a horizontal bar chart to show data for numerical comparisons among different categories, such as, comparing categorical data and for horizontal comparisons.
