### Version 5.5.0 ### Link to Minimal Reproduction https://codepen.io/Artignan/pen/vEELGqm ### Steps to Reproduce 1. Make an y-axis with logscale and big values 2. Add an datazoom on y-axis ### Current Behavior When using a logarithmic axis, the dataZoom component doesn't behave correctly for lower values. The zoomed range does not follow the logarithmic progression — pixel movements in the dataZoom slider are linearly mapped and do not match the corresponding distances on the axis. This leads to inconsistent zoom behavior, especially for small values. ### Expected Behavior The dataZoom component should respect the logarithmic scale of the axis. When the axis is set to 'log', pixel movements in the dataZoom slider should map proportionally to the logarithmic spacing of the axis ticks. This would ensure consistent zoom behavior across the entire scale, including for lower values. ### Environment ```markdown - OS:Mac OS Sequoia 5.4.1 - Browser: Firefox 137.0.2 - Framework: Echart 5.5.0 ``` ### Any additional comments? _No response_ -- This is an automated message from the Apache Git Service.
