By default, the graphs are 480x480 pixels in size, at a resolution of 72 dpi (6.66x6.66 inches). Increasing the resolution will increase the size (in pixels) of the text and graph elements. This occurs because the size of these elements is relative to the physical dimension of the graph (e.g., 4x4 inches), not the pixel dimension of the graph. Res=300 specifies that you need a figure with a resolution of 300 dpi. The figure file named 'test.tiff' is saved in your working directory. Change width and height in the code above depending on the desired output. Note that this also works for other R plots including plot, image, and pheatmap. Matplotlib - How to plot a high resolution graph? Ask Question Asked 4 years, 3 months ago. Active 1 month ago. Viewed 144k times 92. I've used matplotlib for plotting some experimental results (discussed it in here: Looping over files and plotting. However, saving the picture by clicking right to the image gives very bad quality / low.

If you need to create a high resolution image of your Excel chart for a manuscript/journal then the usual cut & paste approach generally only leads to a poor quality 72dpi image often with a bad case of the jaggies.

A Solution

The Resolution Of A Story Happens When

Here is one, relatively straightforward way around this problem. It uses a graphics program called IrfanView (IV) which can be downloaded here . Other imaging programs such as Gimp and Imagemagick can also be used but I’ve found that IrfanView is the easiest for this process.

Once IrfanView is installed you need to configure an option as follows (this only needs doing once)
From the menu: Options:: Properties/Settings :: Select Plugins in lef-thand list :: ‘PDF Options button :: In loading options, select Use(new).. and ‘set DPI’ change from 96 to 300

Now generate your chart/plot in Excel and resize as desired.
Open a new blank presentation in Powerpoint
Copy the desired chart(s) in Excel
Paste-Special the plot(s) into Powerpoint, one to a slide. The key this here is that you paste it as an Office or Excel chart/image object
1. File/Save-As PDF
Run IrfanView and open the PDF file created above (dragging it into the open IV window is easiest)
1. Now repeat the following steps for each page/image:
  1. File/Save As and select JPG
  2. A pop-up options window will appear – use the ‘slider’ to set the quality to good then click save

To check that this has worked, find your newly created jpg file in Windows Explorer and right-click on it. Select Properties and then select the Details tab. Scroll down a bit and check that both the horrizontal and vertical DPI setting is 300.

Background

BMP, JPG, PNG & GIF are all RASTOR image file formats which is a grid of pixels – (x,y) coordinates each describing the colour of a dot at a particular location. These are commonly used for storing & displaying photos. The problem is that when they are over enlarged the quality can deteriorate and straight lines can become jagged.
VECTOR image files on the other hand store the mathematical equations of the components that make up the image (e.g. lines in a graph) and so can be enlarged as much as desired without any loss of quality.
Vector files tend to be much smaller than Rastor files however they generally need converting into rastor files before they can be used – e.g. on a web page.

Resolution is a 2012 American horror film directed by Justin Benson and Aaron Scott Moorhead, written by Benson, and starring Peter Cilella and Vinny Curran. Cilella plays a graphic designer and father-to-be named Michael who, after receiving a troubling video of his former best friend Chris via email, travels to a remote cabin to save his drug-addicted friend, played by Curran. The 2017 film The Endless shares the same creative universe as Resolution, and may be interpreted as a partial sequel.^[3]

Plot[edit]

Michael Danube, a professional graphic designer who lives in the city with his pregnant wife, receives an email that contains a video of Chris Daniels, his former best friend. Chris, a drug addict, has retreated to a remote rural area and has become delusional and erratic. A map is included with the video. Despite the objections of his wife, Michael makes one last attempt to save Chris. He promises to return after one week and follows the map to a run-down house, where he hears Chris ranting and shooting a pistol. Chris reacts positively when Michael cautiously announces himself and invites him in, ranting about various subjects. When Chris refuses to go into rehab, Michael uses a stun gun to subdue him and handcuffs him to a pipe. Michael returns from a shopping trip and sees Chris trying to cut through his handcuff with a toothbrush. In the morning, Michael uses the stun gun to stave off an attempted attack by Chris.

Later, Micah and Billy arrive and tell Michael that Chris is holding their drugs, which they want back. Chris warns Michael not to mess with them, as they have become more violent and unpredictable since Michael last knew them. Michael takes a walk and meets members of a UFO religion, then returns to the house and finds a set of strange photographs. Micah and Billy return, but they are scared off by Charles, a tribal security guard who tells Michael that Chris is squatting on reservation land. Michael gives Charles a bribe to allow them to stay for five days. After they discover creepy film footage, Chris claims that he never sent any emails or videos. Michael finds a book full of creepy campfire stories on their doorstep, and, when he returns the book to the library, finds film slides. Confused by the items that seem purposefully left for them to find, Michael suggests that it is a prank by Billy and Micah, which Chris dismisses.

Michael continues to find conspicuous clues strewn about the area. When he bribes Charles for information, Charles warns him off and tells him that French students used the area for research. They encounter a con artist who offers to buy the house, but he leaves after Michael reveals that they are only 'renting'. When Michael rewatches the video he received in the e-mail, which has changed, it now shows an argument that Michael and Chris had moments before. When Billy and Micah return, they kill a dog that Chris had adopted, and Chris reveals that he is suicidal. Michael tracks down the dog's original owner, an archeologist named Byron who was a member of the original French research team. Byron believes the area is not haunted; instead, something there desires stories. Byron stresses the need for a beginning, middle, and end. Alarmed by Byron's eccentricity, Michael leaves and returns to the house.

As more clues suddenly appear from nowhere, the film projector Michael has been using now reveals the gruesome death and funeral photos of himself and Chris. Michael's laptop suddenly plays a video that depicts their own violent deaths at the hands of Micah and Billy. Confused and scared, they flee the house, only to find a CD that has a recording of Charles murdering them and burning down the house. Chris insists that they leave the property immediately, but Michael does not want to bring the curse home with him; instead, he wants to attempt to appease the entity. When Chris and Michael return to the house, they witness Charles kill Micah and Billy before setting the house on fire. Chris and Michael panic; Chris breaks down and finally agrees to go to rehab. Their joy over achieving a happy ending to their story is abruptly cut short when the entity angrily confronts them. Chris apologizes profusely, and Michael asks the entity, 'Can we try it anot
