C# | Chaikin algorithm – Calculate the coordinate points of the smooth curve corresponding to the polyline

Chaikin algorithm – Calculate the coordinate points of the smooth curve corresponding to the polyline This article will introduce an algorithm for calculating the coordinate points of a smooth curve corresponding to a polyline. This algorithm uses the Chaikin curve smoothing method to adjust the smoothness and accuracy of the curve by controlling the tension […]

echarts combines stacked columns and polylines and zooms the chart

ECharts official website address Apache EChartsApache ECharts, a JavaScript-based data visualization chart library, provides intuitive, vivid, interactive, and customizable data visualization charts. https://echarts.apache.org/zh/index.html Implementation renderings 1. Prepare dom for echarts Be sure to set the width and height, otherwise the chart will not be displayed. <div style=”width: 100%; height: 328px;” id=”institutional-user”></div> 2. Set/get chart data […]

echart displays horizontal and vertical lines on polylines (horizontal and vertical lines are displayed along polylines)

The product has a requirement to display the horizontal and vertical coordinate system on the echart polyline. By default, echart’s axisPointer is displayed at the current position of the mouse, which does not meet the requirement, so it is implemented using markline Online examples and source code First the renderings Implementation ideas The x-axis of […]
