如何在MATLAB图中显示图形的缩放部分？

Question

我在Matlab图上有大约四个系列的数据，其中两个非常接近，只能用变焦区分。如何在查看器的现有绘图中描绘缩放部分。我检查了类似的帖子，但答案似乎很不清楚。

我想找到这样的东西：

Answer 1

以下是如何使用MATLAB执行此操作的建议。它可能需要一些微调，但它会给你结果：

draggable-section__item draggable-section__item--masonry pin-type-${pin.type}${new_class ? (' '+new_class) : ''}

请注意，class_name(){ let new_class; let pin = this.props.pin; let promises = []; if(pin.type == "text"){ var length = pin.value.length; if(length > 200) new_class += "width2"; if(length > 500) new_class += "height2"; return `draggable-section__item draggable-section__item--masonry pin-type-${pin.type}${new_class ? (' '+new_class) : ''}`; }else if(pin.type == "image"){ this.get_image_dimensions(pin.value).then(function(img){ let w = img.width, h = img.height; if(w>h){ new_class += "width2"; }else if(w<h){ new_class += "height2"; } return `draggable-section__item draggable-section__item--masonry pin-type-${pin.type}${new_class ? (' '+new_class) : ''}`; }) }else if(pin.type == "embed"){ new_class += "width2 height2" return `draggable-section__item draggable-section__item--masonry pin-type-${pin.type}${new_class ? (' '+new_class) : ''}`; } } 的单位与轴单位相似，而function pan = zoomin(ax,areaToMagnify,panPosition) % AX is a handle to the axes to magnify % AREATOMAGNIFY is the area to magnify, given by a 4-element vector that defines the % lower-left and upper-right corners of a rectangle [x1 y1 x2 y2] % PANPOSTION is the position of the magnifying pan in the figure, defined by % the normalized units of the figure [x y w h] % fig = ax.Parent; pan = copyobj(ax,fig); pan.Position = panPosition; pan.XLim = areaToMagnify([1 3]); pan.YLim = areaToMagnify([2 4]); pan.XTick = []; pan.YTick = []; rectangle(ax,'Position',... [areaToMagnify(1:2) areaToMagnify(3:4)-areaToMagnify(1:2)]) xy = ax2annot(ax,areaToMagnify([1 4;3 2])); annotation(fig,'line',[xy(1,1) panPosition(1)],... [xy(1,2) panPosition(2)+panPosition(4)],'Color','k') annotation(fig,'line',[xy(2,1) panPosition(1)+panPosition(3)],... [xy(2,2) panPosition(2)],'Color','k') end function anxy = ax2annot(ax,xy) % This function converts the axis unites to the figure normalized unites % AX is a handle to the figure % XY is a n-by-2 matrix, where the first column is the x values and the % second is the y values % ANXY is a matrix in the same size of XY, but with all the values % converted to normalized units pos = ax.Position; % white area * ((value - axis min) / axis length) + gray area normx = pos(3)*((xy(:,1)-ax.XLim(1))./range(ax.XLim))+ pos(1); normy = pos(4)*((xy(:,2)-ax.YLim(1))./range(ax.YLim))+ pos(2); anxy = [normx normy]; end 的单位介于0到1之间，与MATLAB中的areaToMagnify属性类似。

以下是一个例子：

panPosition
