Question

我有一种方法可以定义 Google可视化API提供的动态图表中的气泡颜色？我不想使用默认颜色方案。

提前谢谢。

Answer 1

我没有找到一种内置的方法来做到这一点。但是，您可以做的是为每个气泡分配一个“颜色”变量。然后，您可以将气泡的颜色设置为此变量。我发现，对于3个气泡，将1设置为1，将另一个设置为1.5，将第三个设置为3个项目合理得好（在默认配色方案中，黄色项目非常差）。这种方法可以让您对配色方案进行有限的控制。

这是2017年，我还没有找到一个很好的更新。所以这是我提出的解决方案。 HTH。

#Define the directory containing your .pdf files
$mydir="$env:USERPROFILE\Desktop\New folder"
function print_files($mydir){
    #The purpose of this counter is to number your .xps files
    Get-ChildItem $mydir -Filter *.pdf -Recurse | Foreach-Object {
        #For each .pdf file in that directory, continue
        same_time $_.FullName
    }
}
#The following function keeps checking for a new window called "Save Print Output As". When the window shows up, it enters the name of the file and press ENTER.
function enter_my_names($fullname){
    $wshell = New-Object -ComObject wscript.shell;
    while($wshell.AppActivate('Save Print Output As') -ne $true){
        $wshell.AppActivate('Save Print Output As')
    }
    $basename = [io.path]::GetFileNameWithoutExtension($fullname)
    #This is where the name is actually entered
    $wshell.SendKeys("$basename")
    $wshell.SendKeys("{ENTER}")
}
#The following function launches simultaneously a print job on the input file and a function waiting for the print job to show up to name the file.
workflow same_time{
    Param(
        $fullname
    )
    parallel{
        Start-Process -FilePath $fullname –Verb Print -PassThru
        enter_my_names($fullname)
    }
}
#MAIN PROGRAM
#Here the script saves your current printer as default
$defprinter = Get-WmiObject -Query "Select * from Win32_Printer Where Default=$true"
#Queries for a XPS printer
$printer = Get-WmiObject -Query "Select * from Win32_Printer Where Name='Microsoft XPS Document Writer'"
#Sets the XPS printer as Default
$printer.SetDefaultPrinter()
#Starts the main job
print_files($mydir)
#Sets the old default printer back as default again
$defprinter.SetDefaultPrinter()
#This is a small delay to be sure everything is completed before closing Adobe Reader. You can probably shorten it a bit
sleep 5
#Finally, close Adobe Reader
