R 创建具有特定网格线、标记颜色、背景颜色和特定字体的生动且有光泽的反应性绘图
您好,我有一个简单的闪亮应用程序,我在其中创建了iris数据集中变量的散点图。我想要的是能够以某种方式修改绘图。首先,我希望能够为每个轴设置网格线的限制(例如,1),然后将背景颜色设置为白色,标记颜色设置为蓝色,并添加趋势线R 创建具有特定网格线、标记颜色、背景颜色和特定字体的生动且有光泽的反应性绘图,r,ggplot2,shiny,plotly,R,Ggplot2,Shiny,Plotly,您好,我有一个简单的闪亮应用程序,我在其中创建了iris数据集中变量的散点图。我想要的是能够以某种方式修改绘图。首先,我希望能够为每个轴设置网格线的限制(例如,1),然后将背景颜色设置为白色,标记颜色设置为蓝色,并添加趋势线 首选样式:绘图标题-Calibri(或类似),10磅,粗体, 深灰色 轴标题-Calibri light(或类似),16磅,粗体,深灰色 轴编号标签–Calibri,11磅 数据标签–Calibri,9磅,黑色 数据标记-暗 蓝色圆圈 我不知道ggplot2中是否提供了所有
功能(输入、输出){
输出$lx1好的,很抱歉延迟了响应,但这里有一个工作示例,可以更改您请求的所有功能。它比我介绍的要复杂一些……Calibri不是内置在R中的字体,所以需要使用包加载它。然后,您想要更改的大多数选项在参数中都很简单,但不是需要在看涨期权中更改悬停文本。希望此示例对您的代码有所帮助

通过快速搜索,plotly将允许在plotly输出中显示在ggplot
中设置的所有基本主题选项。您正在考虑的所有选项都将通过ggplot
的主题()
语句。请参见此处以供参考:…希望这有帮助!它有一些东西,但不是我需要的。我认为我应该只使用plotly而不是ggplot2。无论如何,感谢通过ggplot
的主题?所有这些选项都可以更改。fontface
可以设置为粗体,family
可以用来更改字体,color
可用于更改字体颜色,数据点形状和颜色可在几何点()内更改
option等…如果您愿意,我可以复制一个不相关的绘图,显示其中一些选项。如果您愿意,我会很有帮助!我可以更改网格线限制吗?例如,不是0-2-4-6-8,而是0-1-2-3-4-5-6-7-8。因此,使用尽可能多的这些选项进行复制将是一个伟大而完整的答案,我将接受它!一个任务ion..这是一个小细节,但如何将绘图的默认灰色背景从灰色更改为白色,以及将网格线从白色更改为灰色?
