[英]Trying to make a uniform colorscale for each of the bar subplots in plotly (python)
I have created a graph with 8 subplots corresponding to the energy production of each wind turbine in a farm per year.我创建了一个图表,其中包含 8 个子图,对应于一个农场中每个风力涡轮机每年的能源生产。 Each subplot corresponds to a different year of operation.每个子图对应不同的运营年份。 I managed to get a nice colorscale applied to each of the subplots but each of the colorscales has a different range (based on the data in each of the subplots).我设法将一个很好的色阶应用于每个子图,但每个色阶都有不同的范围(基于每个子图中的数据)。
I would like to make one where there is a “global” colorscale and the values in each plot correspond to the fixed colours.我想制作一个“全局”色标,并且每个图中的值对应于固定颜色。 I would be grateful for your suggestions.我将不胜感激您的建议。
