@helgasoft Interesting finding! Let's hope for the that the changes gets merged. Until then, we'll have to use such workaround. The example code that you provided, uses ECharts to render a dual-grid logarithmic bar chart that distinguishes positive and negative values. It first imports the ECharts library, selects an HTML element with the id "main," and initializes the chart instance. A set of sample data and category labels is defined. A helper function computes the closest power of 10 for each data point to determine a suitable starting value for the logarithmic y-axes. The data is then split into two arrays: one for positive values and one for negative values (converted to their absolute values for proper logarithmic scaling). The configuration defines two grids and matching axes. The top grid (with a hidden x-axis) displays positive values using a standard logarithmic scale, while the bottom grid displays negative values on an inverted logarithmic scale with custom tooltips and labels that prepend a minus sign. Finally, the chart is rendered by applying this configuration to the initialized ECharts instance. -- This is an automated message from the Apache Git Service.
