[Dashboard] How to create a line chart?

Post by IoTStudio Support »

這個流程會定期生成一個 0~50 的隨機整數,然後使用 ui_chart node 顯示這些整數的變化情況。在 AIC IoT Studio 中,可以使用 Random node 代替 inject node,使用 Function node 代替 function node,使用 Time Series Chart node 代替 ui_chart node。
This flow to gen a 0~50 random integer in period.
Then use ui_chart node to show those integer value.
