Conclusion
Coordinates are esntial to data visualization with echarts. They are ud to define the points that will be plotted on the graph. The coordinates vary depending on the type of chart being ud. In line charts the x-axis usually reprents time or a unit of measurement like temperature or weight while the y-axis usually reprents the values of the measure being charted. In bar charts the x-axis usually reprents the different categories and the y-axis usuallyreprents the categories’ scores. In pie charts the x-axis reprents the angle in degrees that each slice of the pie reprents and the y-axis reprents the percentage that each slice reprents.。
